Async Attribute: The async attribute loads the script asynchronously.

[@johnnelly473]

Some people have been trying to learn javascript for years and still not learn it. The reason is because javascript is normally taught on concepts level. The ending of each code is on the console. It should be on a UI results level, how it works on a UI, kind of like w3schools but on video format. Learning how it looks on a console will never stick on a learner's memory, because it is incomplete. But if they learn in portions all the way through the ending (html being the ending), they remember something. But if the ending is a console, they rarerly learn.

Hi Mosh, I just finished this course and I love it. I think now I can do your React course!

[@mikkeljrgensen3850]

I've basically locked myself inside 'the lab' for approx. 15 months learning Python, Django, CSS and much much more, and during this interval I've seen and read a LOT of tutorials on coding. What usually bothers me is that these instructors clearly know a lot about coding while having absolutely no sense of pedagogical approach. You don't have this problem, and I'm grateful to have found your videos. I can hardly wait to dive into React now, as I expect that tutorial to be of the same quality as this one. I already knew most of the subject matter in this video, however it did clear up the confusion regarding let vs var in mere seconds. And I got answers for a few things that I'd been wondering about and learned a few fancy little tricks, so without further adieu: Thank you. You're the best.

I already know JavaScript and was looking for a video for my son. Mosh is such a good presenter that I kept watching anyway.

Dear Mosh, I am a complete novice trying to learn coding. This class has made me confident and taught me well. Thank you!

[@torgal786]

Once I saw your this video... now am taking Java script very seriously.. thanks a ton Mosh

[@MaazShaikh-ji2fq]

You know what feeling of "mind opening" we get when we learn something new thoroughly. This video gave that feeling to me multiple times. First time I understood something I liked the video. Then understood 2-3 more things so subscribed. And after that here I am commenting this long message.

I am from Brisbane, Australia and am a complete novice at computer programming. I tried the Harvard introduction to computer programming online course on KZbin, which started off strong but in the second lecture starting talking about C language and just assumed a whole bunch of knowledge and the whole thing became non-sensical. Thank you for your attempt to clearly explain how this works but it starts to unravel pretty quickly in terms of what you say to do and then what is shown on my screen, which is different to what is shown on your screen. For example, on my screen after following exactly what you said I get "Hello World script src="Index.js"" rather than just "Hello World". Also "Alt Cntrl i" on Windows doesn't bring up the console tab, or provide any response. When I go to the inspect option, I get a page with the following error: "Uncaught (in promise) Error: A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received". Where would you suggest I go to be able to learn in a real time or face to face environment where these errors and all my questions can be explained and rectified? Thanks again.

This JavaScript tutorial for beginners helped me a lot in learning the basics of JavaScript. Thank you very much, Mosh!

[@maryambahr118]

Great explanations and categorization of JavaScript's basic but fundamental concepts where beginners could start with less confusion. Thank you.

Love the way how simple he (Mosh) make every complex topic

[@thedislikebutton3564]

I have 2 hours on this project and this video is 1 hour, that means i have 1 hour to do my project.... wish me luck

[@ZapRodil461]

Thank you so much for this! It was super clear and fun to watch

This is so informative, it's sad we pay so much money for our Lectures but don't get such quality learning experience

Excellent video! I've spent the last couple of years learning Python, and I'm looking to expand my skillset with JS. This is a clear, concise, and easy-to-follow video. Thanks!

[@simsandwins8998]

....you mean it takes years to learn python?!! oh noooo =(

[@siegvash]

@@simsandwins8998 You never stop learning tho. Once you "master" a programming language, at least 4 new ones drop

[@dziolex2190]

@@simsandwins8998 a programming language by itself is pretty easy to learn, it's mostly about learning how to use it, not to mention libraries which can add a lot of new statements.

Can anyone tell me, which theme he used in this video?

Came back to programming after a year and this was the tutorial.

I'm a literature student, I just wanted to learn the basics of java script out of interest yet I was a little hesitant this video bought my confidence ❤, thank you🌹❤

[@terrancepinkney777]

What a great tutorial sir! I am a brand new aspiring Dev and this intro video really opened my mind up about how cool JavaScript really is. I totally understood pretty much everything you talked about and even tried some different functions and tasks on my own. Thank you for the time and effort you put into this video it was well worth it.

[@LiveMahs]

7 months later, where are you at now? I hope it's going well man!

Hello my friends, I make JavaScript Projects on my channel every week, and I help beginners and intermediate javascript programmers to develop their skills by doing projects, check my subscribe if you are learning javascript!

I really enjoyed this tutorial, what a great way to get started with Javascript ! I also want to mention that we have optionally-typed programming languages that allow both dynamic typing and static typing. One of such languages is Dart.

I want to have a job in either UI design or cybersecurity. I would have to learn JavaScript in both, and in the 48 mins I watched this, I’ve learned a lot!! Thank you Mosh!! 😃💗

[@needjuice]

Thank you Mosh for this tutorial! No one could teach me better, even a boot camp. You simplified the tutorial very well and you're good at explaining, thanks again!

[@mendrikamaminiaina8297]

Thanks a lot Mosh! you're a real inspiration for me! I learn so much even i'though and acquired so much value

[@vrushalimali2238]

Very good course. All concepts are explained in simple way so that we can easily understand it without any confusing. I have gone through many courses which are very confusing to understand the concepts. But this course is very good, Real-time examples are very helpful to relate the concepts with real world and we can easily memorize those examples. Thanks for teaching 🙂

For anyone having troubles at 18:00 with the "name" variable on Windows, change it to sth else as its a Windows property, in the video Mosh was using macOS so it worked

[@pipitgusmayanti8342]

'name' is not a Windows property, it's a property of the 'window' global variable (and 'window' here is not referring to Windows operating system)
