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.

[@thalperi2]

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.

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

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.

Great editor colors. Great volume. Just a pleasure to watch.

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.

[@rollacoast]

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.

[@invictuz4803]

I leave it at 2 for parts that read like a book, and put it back to 1 for parts where you need to think about every word.

[@HuiXiong]

Thank you

[@AmberLowe111978]

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.

[@MBkingsoft]

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!!!!!

[@DominicVictoria]

40:58 The reason why I love this tutorial. A lot of YT tutorials are misleading and inaccurate. Hoisting functions to the top just doesn't make sense especially when you have more than one function in that file.

[@danielllalivedutoit3175]

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

[@pianopov]

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

[@RSfairat]

OMG it's a real gem! Bought the full course after watching first 2.5 hours.

[@yiga6253]

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.

[@advers1078]

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

[@badqual]

Thank you so much Tony, I purchased 12 hours, it is life changing lesson.

[@TonyAlicea]

VideoTutorial Thanks!

[@widebandrecords902]

Tony Alicea Keep it js core bro..

[@widebandrecords902]

VideoTutorial Yes, learning the core is essential, *J-query* and others were made due to many lazy people who obviously didn't read the *J-S* book, and because of that trend and at the same time mobile browsers were booming, *Jquery* team added the cross browser attributes so now for many of the frameworks and libraries are now somewhat needed for money making sites who always need to reach almost every browser..

[@widebandrecords902]

VideoTutorial and when i say lazy i mean they don't want to learn or even trial and error, but rather never understand JS fully enough and sound stupid trying to explain *J-S* infront of a big audience just because they lead a team of maybe more talented JS programmers who as a team made a successful web product..

[@badqual]

Wideband Records agree with you,when ever I see $ I lose inspiration and uncomfortable with coding.

[@getmorpheeus]

Just finish the whole course, it's just amazing !

[@apexwindowcleaningservices4457]

Anyone trying to learn programming in any language will learn a lot from this. I'm currently learning Java, not JavaScript but I have learned a lot from this video that also help me learn Java. Excellent teacher.

[@quantum954]

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.

[@igbokwelaurence5882]

WOOOOOOW. I had to sign in to comment on this video, and i never do that. Tony you are fr#$%ng incredible. I'm sure 5 yrs to come this video will still be useful to many. May God bless you for this

[@山田ちゃん]

I am rarely linking a video but this deserves a like from all my accounts

[@logixindie]

2:37:40 You know you write codes too darn much when you end a sentence in English with a semicolon;

[@Devstackr]

:)

[@richarddominguez7218]

Hahaha

[@kevalshah09]

Hands down one of the best javascript course i have come across. Really makes it interesting and explains why the Javascript the way it is

[@TonyAlicea]

Thanks so much, glad it has been helpful!

[@kylepotter3105]

Thank you, all the other tutorials I've come across just start by firing off code that means nothing to me. Understanding this has made everything so much easer. Thanks Tony!

[@adams7930]

Great work! I've looked at a few JS tutorials, both text and video, and none of them mention this kind of stuff. It's pretty scary when most guides don't even mention the fundamentals! Thanks for the video, I've already watched one half today and learn't a lot. : )

[@timmytim9054]

Agreed. The guy really knows what he’s talking about.

[@laistomazz]

I'm still watching, but I just wanted to thank you for saying "guys AND girls". Thank you, for real.

[@badqual]

[@badqual]

***** watch your language mate, stay human and have a little respect for everyone it wont cost u anything, it is about equality it has nothing to do with feminism.

[@laistomazz]

***** Poor guy, the bad feminists who stole your icecream, we ARE EVERYWHERE. How are you gonna live now? I wrote a comment saying a good thing, with a compliment, with nothing close to a "whining" and then there's some poor guy whining about whining feminists. Oh, the irony of it all. hahaha

[@emmanuela.2932]

It's like "ladys and gentlemen", it's about good manners, not feminism. He even should say "girls and guys", because himself is a guy, he shouldn't put himself first, to be really courteous. That being said... Death to feminism, it's pure ignorance.

[@bendover4728]

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

[@noctap0d]

This is one of the best JavaScript videos on KZbin. Thanks for your hard work.

[@TonyAlicea]

Thanks so much!

[@learnAndfun101]

The best thing is when people are happy about your work . Ans that for me is eay more precious than earning money . Thanks Man !
