[Rafael Magalhães Braga de Souza]

you, sir, are a hero.

[Julyus Andreas]

you da real mvp. big thanks

[Cléber Santos de Oliveira]

I was looking just for it! Thanks mate.

[K Ahmed]

@tony alicea kindly include this in your video summary..

[Rational Raven]

I wish I had a video like this for every programming language, it's so in-depth, I really like learning the underlying philosophy of a language rather than just the basic functionality.

[Mickey P]

Good news, except for the hoisting all the rest works pretty much the same in all languages. Operators exist just you have static typing. The scope and outter scope is a general concept in all languages. This is basically a course in computer science

[The Design Creative]

26 minutes in and already I am ready to buy every single course you make . What an inspirational teacher you are. I feel like Neo when he unplugged from the matrix and said “I know Jujitsu”

[David Morgan]

*Kung Fu

[Ratnesh Chandna]

Same!

[Michał Kazimierczak]

I watched whole 12h course 3 times (I watch it every year since bought it), probably the best javascript course I have ever seen. I have 4 years experience but still learned new interesting things. During job interview I knew every answer about javascript (probably better than interviewer), thanks to this course. Even if it's old ES5, it's still worth buying because new javascript like ES6, ES7... is usually transpiled to old ES5.

[Tony Alicea]

That’s awesome Michal! Thanks for being a student! I will be adding more ES6 content to the course next year.

[Jessica Gladstone]

I bought this course years ago and I still use it to refresh my basic concepts. When I have job interviews and they ask about JS fundamentals, my thought process goes right to this course! It is clear, concise and delivered in a slower manner so you can absorb everything he teaches. I love this course! I recommend this course to everyone I know who is stuck on JS. I think Tony Alicea is brilliant!

[Kody Sherrer]

Just in the first 15 minutes i was blown away by how well thought out and put together this course is, i will most likely be paying for the rest. Keep up the hard work, youre an excellent teacher.

[Jarryd Phillips]

How's your JS coding going? Did you complete this course?

[Glenn Williams]

Amazing clarity. A teaching philosophy and presentation that is totally spot on. Most of us dive in to things to get the job done. I've been using JavaScript as required for 15 years but sometimes going back to first principles, when guided by a really good teacher as you are, can really pay off. The part where your first real JavaScript program is a blank screen is absolute genius - that might sound strange if you haven't seen it. Thank you.

[OUESLATI KHALED]

same here :p

[Antonio Fuller]

A blank screen?!! LMAO

[Marcus Junior]

You speak English very slowly, and this is good for those who are not native to the language, easier to understand. Keep it up. Thank you

[Myugly code]

Thank you for clarifying why I liked this video so much! It gave me time to think and understand with out pausing or slowing down the video!

[InfiniteTurbo]

B

[Victor Barzana]

I went like in 1.75x speed and that's fine as well. Great video, although I'm still confused about state management, tons of unnecessary re-renders of the whole app and much more. We are not quite there yet. But I have to admit this is easier to understand for newbies

[Devs Like Us]

That is such a great point. Will remember that!

[Сергей Рудиков]

@InfiniteTurbo р,что

[S.R. Aman]

I did this course 2 years back, now I am here again just to say thanks man. This is the best thing I did in my life.

[Amine A]

really? :/

[Mitchell Mack]

Can you make a mobile app? I pay cash

[VeeTech]

@Mitchell Mack Let's do it.

[Joel Emal]

Adding a comment as this is great content and still valid 7 years later. The best part is that way the information is delivered feels like a college lecture. This has been very helpful!

[Lance Tschirhart]

I've gone through a bunch of udemy courses, and I consider this one the most essential. These first 3.5 hours are by no means the most interesting or informative (believe it or not)

[David Taylor]

Most of the technical videos here on youtube are presented by people with an adequate grasp of their subject matter - I believe. But this guy actually knows how to teach. It is unlikely that any person with a basic understanding of Javascript can watch this video without understanding the material. Keep 'em coming, Tony.

[Tony Alicea]

David Taylor Thanks David!

[RAM]

Tony Alicea Sir how to download your video. I'm 2014 passout sir. I'm interested in front end development. Now I'm taking course on this, but I'm getting confused. Please help me sir. If you can please send me html,css,javascript videos to my mail sir.

[Cameron Chardukian]

Agreed with this exactly

[tamir]

At 2:09:45 you, correctly, say "the same associativity". However, 9 seconds later, your mouse is hovering of the same 'order of preference' despite your repetition of "associativity". At 2:11:23 you remove all doubt about which column is, in fact, declaring associativity. I concur with David that this is an excellent course and I will be continuing to follow you. Please put up some application building blocks type courses that show how to manage typical functions of most high traffic websites. Much thanks for your time and abilities.

[YouHolli]

Any person with a basic understanding of Javascript knew 97% of this already. Where are the "weird" parts?

[Amber Lowe]

This 3 hour course is so amazing! Understanding the global lexical environment and execution context is so important in regards to where things sit and how to understand how JavaScript works under the hood. I wish that this teacher had a million other videos!! I should have paid Tony the amount of money it took me to earn my degree in computer science. In three hours i understand more this topic than I did in four years.

[Jon Krzton]

As someone who has spent the last month trying to learn JavaScript, this has been an asset. Extremely well laid out, clear and concise explanation, and provides an understanding of "why" JS works the way that it does. You should consider being a teacher. Thank so much for your help!

[Kay Drechsler]

I had a lot of fun following the video through and bought the whole 11.5 hours package afterwards. I don't know exactly what it is that I appreciate about your course but your style of phrasing, rhythm of speak and focusing on the parts that are confusing for beginners is just awesome. Keep up the good work!

[jeremy mitchell]

Tony, I have really been struggling with the JavaScript. This video seemed to pull together everything I was struggling with and explain it in a new way that I can understand. Can’t wait to take the rest of the course. You have rejuvenated my excitement for wanting to learn JavaScript. Thank you Sir!!!!!

[Robert Zeurunkl]

Even though I am a seasoned JavaScript developer working in a full stack environment, writing enterprise-class business applications that target the core activities of the airline company that I work for, this video was super useful even for me! I do not always know the correct names for some techniques and practices, and this course was very good at properly identifying and defining everything. I'm thinking of buying the full course, but would like to know if the Udemy link here is the *latest* version of this course, or if you've some revised or expanded version somewhere? Preferably something that covers Promises and async/await.

[Strategic Designs]

One of, if not, The Best explanations of a programming language I've come across. Thank man. Keep up the good work.

[Dask]

A tutorial like no other, really digging into the skeleton of the language Much appreciated!

[Tony Alicea]

Thank you!

[Donnie XL]

this was by far the greatest Javascript tutorial I've ever seen. God bless the algorithm as well as this man for such a well explained and incredibly competent explanation of Javascript.

[Hassan Mirza]

A very well explained tutorial. I wish someone had taught me programming like this years ago during my undergraduate studies. Make Python and R language programming tutorials, please.

[Human Evolution]

Love your clear concise simple teaching style of objects. So much better than other videos I've watched. Subscribed!

[João te ajuda]

Besides the great content, an excellent video to practice English. Excellent audio quality with perfect pace and pronunciation for non native speakers. Thanks for this and congratulations for one more subscriber ❤️

[Raymond Starkey]

Skilled teaching, professional presentation with a genial relaxed style that really works. Lots of reinforcement in the right places. Well done.

[diwaker tripathi]

This was awesome. You love to teach it seems. One of the best videos I've seen so far. Just opted for full course on udemy. Thank you for making some part of it available for free.

[Josselyn Munoz]

You really hit the nail on the head at @11:00 I was one of those that were introduced to front end dev with all the frameworks and Jquery already in place. It was really hard for me to understand what's what.

[Gadi premikudu]

Tony, a) I'm just about to buy your course and b) how lovely it would be to see what you make of ES6, and teach it to us. You are an outstanding teacher, and as such, a credit to the profession and to the species. No joke. Thanks for this work of art.

[Blessing Claudio]

I am a trainer and was looking at ways to find my lost class! You did it! With concise explanation every bit of the code is simple to understand and even the scared students started having smiles on their faces! This is what varsity lecturers should be doing! I am going to purchase the course! Dude thanks all the way from South Africa!

[Martin958]

I am going to buy this course. After over a year of learning to code by myself, this is the first time I have understood why hoisting actually works. The speed of the chat makes it easier to follow as a beginner too. If you are someone already versed in Javascript it might seem slow and tedious to you, but for someone like me this is perfect! And I am understanding stuff that never really seemed to be explained properly before in other tutorials.

[teldrah]

Do you know this nice feeling when you finally understand something that has been bugging you for a while? That bliss of comprehension? I had this several times during this video! Thank you, Tony.

[FefeIsBored]

You mean the Aha-Moment?

[littensy]

Mans knows the meaning of life 5 years later

[Duy]

Does this still apply to today? @teldrah?

[Joseph Davidson]

This is by far the most helpful JavaScript tutorial I have ever done. I have done now half of the course on Udemy and it is so worth it. I feel like I had a false idea of what being a JS developer meant. You are the man Tony thanks a ton!

[Francesca]

You are a fantastic teacher !!! I wish there were more like you 😊 I will be looking at your course on Udemy 👍 Thank you Tony 🙏

[Chris Simmons]

I think the best part of this video is your humble teaching style. You are very patient and thorough in your methods and it was sheer joy to listen and watch your video. Great job! I had a few "aha!" moments which pleasantly surprised me. Thank you!

[Michael PTL Always]

Really appreciate taking time to explain things .. I am currently enrolled in an online bootcamp and many times feel like I am flying through lessons and maybe retaining 20% of what I am learning ... hoisting was a tough one to understand and you take the time to break it down and go over it in detail. Many ... many thanks ... BTW ... I also signed up for your course.

[Vanessa Pham]

I love this style of teaching. You have explained and ingrained fundamental JS concepts better than any other course. I've been struggling fully comprehending JS for months and this was just *BOOM* what I've been missing. Bought the Udemy course just now and am looking forward to finishing it. Thank you!

[Dad with Dumbbells]

Just finished the first three hours and I'm blown away by how well the material is presented. I purchased the full course on udemy for $19 and ended up getting the Angular course for $19 as well. I feel bad only paying that amount.. it's a steal. Keep up the great work Tony! I will definitely be back for more. I'd love to see a React-JS course offered.

[MJ_305]

This has to be the best and most productive lesson on JavaScript I’ve ever watched. I enjoyed it from start to finish and love the way he reiterates the important information. Even the remarkable introduction was an attention grabber. For those of you criticizing the slowness of this lesson, well that it so the average person can comprehend this esoteric part of JS. You can always increase the speed with KZbin’s playback option. You just earned $20 from me brother.

[kai d]

This video is AMAZING! It's filling in all the gaps in my JS knowledge that the course I'm taking - as good as it is - has left me with. Thank you!

[Nanteza Sumaya]

I am immensely thankful to God that HE led me to this video. Tony, you are such a wonderful instructor. I can't seem to find the right words to thank you for taking your precious time to put this whole course up. I am changing careers to take and just completed a coding Bootcamp for web development. I have watched tons and tons of Javascript Tutorials, most of them the instructors speak so fast that it wears down my energy. You speak reasonably slow and passionately take your time while explaining concepts. Thank you! so far none the tutorials I have watched is comparable to yours. I have just bought the full course on Udemy, I hope it leads me to the best JS programmer I can be. Thank you again.

[Alexander Lindgren]

Tony can you please make an updated course on all the ES6 features and maybe combine it with react? Love your teaching style!

[Shabadoo Shabadoo]

Im not learning JS right now but this actually looks dope. Thanks for taking the time to make such a long vid.

[Thomas Sebastian]

The absolute best tutorial ever on JavaScript. The author stays true to his vision throughout the entire course. I am pretty amazed how well they have been put up. Why would one give 3 hrs course for free ? Because, the author believes in his work and it has paid off, as I myself am going to buy the entire lesson even though the price is more than what I can afford for the country I live in. BEWARE: The quality of this material is so good that you might even think twice to refer other tutorials anymore. Tony Alicea You are the man.

[Tony Alicea]

Thomas Sebastian Thanks Thomas!

[bashful228]

Are you living in a developing world country on a developing world wage or lower?

[paulo deleon]

but there's a virus in the website that he wants us to download, did you encounter it? i mean the brackets.io

[Hùng Đỗ Thành]

on 10$, come on! even cost of the internet you were commenting on was more expensive!

[Jack Leone]

@Hùng Đỗ Thành that's was 4 years ago. Udemy has changed since then, believe me, I know. The $10 wasn't always just $10.

[Juan M Cacace]

This is by far one’s of the best tutorials ever made! I passed all my interviews questions thanks to this one :) !!! Thanks 🙏🏻 so much for the explanation!

[x x]

Excellent video, thank you so much for uploading it and for the work you've done

[vibzz s..]

This is the best tutorial i have come across. Your thoughts are crisp and clear. It is as if I am downloading the concepts directly from your brain. I am buying your Udemy course. Also, I will contribute in any other way if possible. If you can create a tutorial on Data Structures and algorithms in Python; it would help me a lot.

[sacredgaming]

Like most, I figure, I was was worried about the age of this content and I don't usually comment, but wow. I am self taught/teaching, and have watched probably 20+ hours of JS courses on other sites. I've banged my head on the wall trying to create my own simple projects, and finally decided to try to learn what others appear to not be teaching... The fundamentals. I have only made it to "The Scope Chain " section and everything just made so much more sense. Definitely going to buy the course.

[Guido DiPilla]

Tony, I purchased the course on Udemy based on this video. Nice job... The way you explained how JS works under the hood, made it much easier for me to understand the language and why it does what it does. Have you updated the course to include more on ES6? Do you have any other courses available?

[FlixVideos]

Tony, you are one of a kind teacher. Good voice. Slow pace. Very, very engaging and educational . I can't imagine why someone would not like this.

[Hanz]

Very well done. I'm an experienced programmer but always baffled on some JS quirks - you nailed them.

[Bob Hiltner]

[Listening at 2x.] Agree with your philosophy 100%: Understand first principles, then the rest falls into place AND is more memorable (or easy to derive from your foundation) . I take a lot of Udemy classes, and the mimicking approach leads to exposure, not understanding, which, to me, is a slower process to get to the end goal of fluency in the topic. Thanks for this great "introduction." Bought the course.

[Jessup Gerald]

This is incredibly thorough and communicated very well. Definitely purchasing the course in a week or so. Thank you!

[Madhur Garg]

This is one of the best JavaScript series, that actually focus on JavaScript the programming language. Most of the other tutorials teach JavaScript with HTML and CSS, which omits basic concepts of JavaScript. I think this is the best. Thanks man!

[Yiga]

I have watch tones of tutorials and this is the best I have seen. Just too good. Lots of concepts I have struggled with was perfectly explained. Thanks a million times. I can't Thank you enough Tony.

[Bartosz Gladecki]

This was amazing! I understood everything and Tony is awesome and speaks in a way i don't get confused. Definitely will buy this course as soon as ill have money. Thank you, sir! You are the best!

[Ariel Mariani]

Great way of explaining everything, you make things more "understandable". To thank you and continue learning, I just bough the combo of this course and the NodeJS one. Thanks again!

[Kvng]

You're definitely awesome. Started learning JS, with only prior knowledge in html nd css fr just a week, and you uplifted my dedication to 1000% into Javascript. 😇

[Randy Miller]

Across many years, this is my single favorite video course, the one I remember most and enjoyed most. I'm going through the entire course a second time (udemy), and am still learning a lot. This Weird Parts course is unique and very special...you don't spend the first half day learning how to add and subtract. You dive right in. Anything you learn is immediately usable across Javascript, its all conceptual. Broad-based.

[Tony Alicea]

Thanks Randy! So happy to have been a part of your journey.

[Steffen Laurens]

Hey Tony, thanks a lot for the comprehensive explanation about Javascript concept, I've been searching for this kind of material ever since I gotten more deeply into front-end development. Your video delivers the messages very clear in each spesific applied contexts even for someone like me who had no programming/IT educational background. Keep doing the Great Work! By the way do you also writes articles? Where can I find it if you do, cheers!

[Tu Nguyen]

1 hour in and I am on Udemy buying the course. After 3 months of jumping from framework to framework not knowing what they did, this video explained it well. Thanks!

[The Daves I Know]

Long term suggestion: If you know anything else with even half the depth that you teach JS and Angular, you should do videos on those too - Linux shell, Databases - MySQL, NoSQL, Server Side languages - J2EE / Python / PHP. You know how to teach well. That skill / gift crosses technology boundaries.

[Tony Lagumen]

You are doing a great job Tony! I like your methods and your teaching technique. The tempo, correct methodological approach and logic of how you deliver concepts are basically right on the spot. Some of the few mentors i have come across in the past does not have that right pace, correct approach when delivering 'pass-on' knowledge therefore, ineffective. Foundations and framework are the keys to building ideas/knowledge. You hit it! I hope you do more of these type of lectures coz i was able to wrap my brains on those concepts and will pretty much will build upon it. Thank you! BTW, Tony is a great name! :-)

[Vasile Midrigan]

I can affirm for sure, this 3.5 hours make a lot more sense than many others pay courses for js fundamentals. I'm very impressed with the in depth explanation and professional approach. Thank you very very much for this truly hard and unique work.

[Francesca]

WoW.... one of the best coding teachers I've come across so far. You really delve deep into the inner workings of JS and is helping me enormously- I defo plan to take your full JS course !!! 👍👏🙏

[Ryan Samarakoon]

Great work, it's good you break down every action you do and your thought process, even for simple things like console.log, it helps broaden your audience and help strengthen through understanding for those who already know.

[Michael Newman]

This video is perfect. I'm a hobby web developer of 5 years and I'm about to attend a bootcamp and try to change my career permanently. This video is giving me a deeper understanding of JavaScript then I've ever had by far. Thank you so much!

[José Palomino]

Amazing, Im in the middle of the video, and I finally understand a lot of the things that I couldn't properly with other courses and books (like javascript the best parts, and Eloquent javascript). I now bought the full course (first time buying on Udemy or any of the online courses). Thanks for the discounted price, I couldn't afford it any other way (I'm from Chile and the change between CLP to US is brutal now).

[Jonathan Eisenmann]

This is excellent! The information here is already changing the way I code. I am not guessing anymore. I am understanding and confident about how and WHY my code works. I have purchased the full course and am continuing to grow a rich understanding of the hows and whys of JavaScript. Rest assured the rest of the course continues to provide deep and valuable tools. Thank you Tony Alicea for providing the first few hours free as I am usually a cheap skate and would not have considered paying without confidence that this course does answer my questions and makes me a better programmer.

[Shannon smith]

@Intvar by by by n.y nns

[Rossi Meacham]

What a great video! This makes JS accessible - This is amongst a handful of truly useful beginner courses. Thank you!

[Slick Chick]

You are an amazing teacher. You are literally the only instructor that dives deep enough into JavaScript to explain what’s happening behind the scenes aside from Codesmith. I’m very happy to have found u in my search results. This information was exactly what I needed to prepare for a technical interview. 💗

[James Santos]

Thank you Tony! This is really informative and accurate! Well versed and makes GREAT sense!!

[Ivan Rachev]

hands down one of the best, most well explained lectures I've heard about any programming language. good teaching skills man

[Ben Millam]

The first 3.5 hours have been so good, I just followed the link in the video description to Udemy for the full lecture list, and spotted exactly more of what I need explained -- I'm new to programming and JS and this is exactly what I need to better understand others' more advanced code. Thank you!

[Tony Alicea]

+Benjamin Millam Great, look forward to seeing you on the forums! Welcome!

[HunterXHunterIsUniversalConspiracyTheory]

This is possibly the greatest programming tutorial ever. Its amazing for any language not just javascript. Recommend playing at 1.5 speed though. First tutorial Ive seen explain execution context, syntax parsers and environments. Took me years to finally have that 'aha' moment about those topics. Great video.

[Chickee]

Understand vs Imitate. You are so on point! I've been trying to learn JS for more than 2 months now through imitation, and I keep bumping into the same problem and I don't know why. After watching your video, I finally understood why. Thanks a lot!

[Leo Salminen]

I bought the full course and in my opinion it is definitely worth those $19 (and more). All the fundamentals of javascript that you normally never take time to learn thoroughly are explained clearly.

[Usman Iqbal]

A friend of mine asked me to watch this and its worth it. Things under the hood are really exciting. Hats off to Tony for this brilliant tutorial

[ambu]

This is the BEST JAVASCRIPT TUTORIAL!!!! I was learning on freecodecamp, doing the exercises without understanding what the heck I'm doing. Tony explains each concept in detail and repeats the messages so that you can remember! Thank you thank you!!

[Danielllalive Du Toit]

Thank you so much!!! You are an excellent teacher. I hope you continue to develop courses, preferably on everything ;)

[Quantum]

You need to have the right expectations for this course. It's an excellent collection of videos for you if you basically haven't spent any time with javascript at all yet, so you want to learn the fundaments as well as understand the weird parts. Tony takes the time to explain every small maybe 'obvious' fundamental multiple times, which is great if you're a complete novice to javascript. If you already have javascript knowledge and are excited about the weird parts and depths of this great language, the slow pace of the videos and multiple explanations of basic concepts as well as constant demoing in the console of stuff that you already know how it will look like, can be a bit tiring and forces you to constantly hit the skip 5 seconds button or set the playback speed to 1.25 or more. Like I said, just have the right expectations. This course is not only about the exciting weird parts - it's about those AND about all the basic fundamentals of the language, well explained to a high level of detail so that a person completely new to the language can understand it.

[Mariano MF]

I watched almost the first two hours and you convinced me of buying the course. That's hard to do bro. Excellent video!!

[Ålexander Yurchenko]

Same!

[Ben Dover]

I wish someone to make a video just like this one, but about Python.. Great explaining, great video!

[j c]

great video, thanks, just at the start of my js journey. so this is just exactly what I needed, purchased the full 12 hours!

[name = "Matt"]

This was the autoplay for me and I've just got to say that I completely resonated with the learning experience you mentioned at the start. I'm going to uni at the moment and the tutors are not making sure people understand why we code certain things, they're just making sure we can copy what they do. I spoke to someone outside class and learnt more about the content that uni has been teaching in 30 minutes than I had in the 80 hours of study time to that point. I'm not learning JavaScript just yet but when I do, I'll check out your channel and udemy courses.

[Piano POV]

Thanks for your contributions to JS tutorials on KZbin. Great job and very well organized!

[Mitchell Mack]

Can you develop a dating app? I pay cash

[John Colby]

I've programmed for 30 years and have never seen a course that goes into this level of detail. Good job

[Gerard Gauthier]

In the world of programming someone finally takes the time to produce a help video that actually helps and doesn't just copy and paste the getting started page of into video format. Bravo! This is well thought out and well produced and has a solid mission.. Understand how it works and you won't have to memorize every usage case. The only criticism I can think of, and its not really a criticism, it the tempo of the narration.Its a bit slow but it does allow the consumer to think along the way. Great content. Great font size. Great editor colors. Great volume. Just a pleasure to watch.

[Christopher Dean]

My mind functions like this tutorial is made. Excellent. I hate to say it but in today's world others would get bored and move on. I buy books to understand what's going on. Your approach is great. Subscribed immediately. Thank you.

[Meba Kassahun]

I was waiting to finish the whole video before I wrote any comments but I couldn't hold it anymore. I love you man. You are the best. I was really lost in javascript trying to apply concept from other languages that I already know, but you made it really really clear that js is a different animal. And for first time ever I know the reason behind my js codes. Everyone else on youtube teaches us just the syntax but you went above and beyond. Thank you sir. I never thought I would be this excited for JS. Thank You!!!!!

[Jared Stevens]

Just bought the full course on Udemy, this makes so much sense! Please, please, please make more videos. I've been an SE for a year now, and have often been lost in the code trying to understand what it is saying, I spent $XX thousand dollars on a Bootcamp and your $15 course on Udemy blows that out of the water.

[Monkey D. Chopper]

That was an amazingly informative 3 hours, can't believe i sat through it in one go but I'm sure glad i did.

[Finskou]

This is incredible. So clear, so well explained. Thank you so much! Instant sub!

[GaryChap]

Was looking around for some tutorials to assist me teaching someone JS ... and THIS is perfect. This covers most of what I wish EVERY JavaScript coder knew before starting out, instead of just muddling along till they felt (over)confident. I just finished teaching C# in almost exactly this way and it was hell coming up with the lesson plan and materials ... but the end result is a kid that can load, drop and navigate assemblies and side-assemblies and has an appreciation of JIT and IL - we even got into remoting with shared assemblies and modifying object code at run-time for a game world (dropping the old assembly when objects are converged) Now I have a 12 year old wanting to learn JS... personally, I hate JS, so I was looking for some materials to do the heavy lifting - and there's almost nothing out there that matches this for getting the foundations covered before moving on to code, Will definitely check out the udemy materials too... at that price, who can say no : ) This is going to save me SO much time. Thanks Tony. I owe you much beer.

I watched all the material available here. A piece of good work. Readable and well explained. I would love to buy the whole course, but the current situation does not allow me to.

My first lesson on JS programming! Since I have an idea on programming, and I am a mathematician, I am sure when I start coding I will be completely have less difficulties. Thank you. A big beginning

Hello Tony, I just finished Your fantastic Udemy course on JavaScript. I absolutely loved it, as I said in my review, it is hands down the best JS course available out there... I am really really interested to hear your recommendation for a "html/css" course (since you don't have one :-)...) also, more for general learning proposes, which of your courses should I take next, the AngularJS or the NodeJS?

What an amazing work! I’ve recently statred working as a software engineer, and I sometimes encounter a situation that I have to do sth with javascript. I was always confused a bit. After watching this, I could grasp the whole picture. Thanks a lot :)

I bought this course and completed it today. He knows how to teach javascript clearly because he knows the engine that lies 'under the hood' very well :) .This course is far beyond of the other javascript courses. I hope he will record a new series and it covers much more advanced concepts. Thank you for your great effort.
