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

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.

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).

[@kaziupir]

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.

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

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.

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.

I watched at 2x speed. Thanks, it was very interesting to find out some things I didn't know about javascript!

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.

This short video is a very small piece of the amazing video course that i'm about to finish at Udemy. Its good even if you have years on the field. Thank you!!

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!

The world needs your tutelage. I honestly came here on a whim. Started watching your (free) video & just couldn't stop watching. You have really thought about this video. It's just beautiful. You really know your stuff too. You teach things that really require knowing. Your video is gorgeous - pin sharp & I love the way you really zoom into the important code; I've seen many videos where I can't even read the stuff on the screen. Your presentation is impeccable. I've watched an unhealthy number of videos on all sorts of stuff & this is the best of the best. Needless to say I purchased the rest of the course. Please keep it up!

Duncan Carr Wow, thanks so much Duncan! Look forward to seeing you on the course forum!

As i have ADHD and autism i still sat through a 3 hour video. That's probably because i love to code. Love to learn. This is something i have a passion for. It stands out. Thank you for this. This video was chosen out of many other tutorials that i could've chosen. I chose this one. Thankssss

Swade What a great story Swade, keep it up and thanks for being a student!

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!

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.

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

[@TonyAlicea]

Thank you!

[@bendover4728]

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

[@hassanmirza2392]

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.

[@PraiseTheLord95]

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.

I'm taking a college class and the textbook is pathetic compared to this instruction. In fact, all the textbook does is blurt out concepts, shows you obscure examples, and somehow I'm supposed to understand and construct code from that? Thank you for taking the time to provide such quality content. Your presentation method is also unmatched.

[@TonyAlicea]

Kingison Thanks! It's the difference between mimicry and true understanding. Too many books are focused on the number of examples they push out, rather than foundational, conceptual understanding.

[@Bu7MaiD075]

Y’all wake up to this? I put it on before sleeping better than any ASMR or podcast.

[@muzikjay]

The BEST JS video I've found. Just bought this and your Node.js course on Udemy. Thanks man! Great content!

[@finskou]

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