🎉👨🏻‍💻Episode 10: JavaScript Value vs. Reference - of 10 Things JavaScript Developers Should Know But Probably Don't.

[Rashomon]

I never thought "value vs reference" could be interesting, but you enlightened and entertained me at the same time.

I swear Sina if you would upload a video on talking about paint drying, I would watch it twice!! Your presentation is unlike I have ever seen and I have been watching and learning from tutorials my whole life. I mean--the content, the recording, the music!!, the illustrations, humor, the cool animations, the intros, the outros! You have literally made me fall in love with javascript. When I think "javascript", I think "colorcode"! You sir are absolutely amazing! One suggestion I have for your upcoming vidoes is the event loop, I can't imagine how happy I'd be to see a video on that from you.

You deserve a million subscribers. Your teaching concepts are great. It's easy to understand, good pace, and well simply explained. I hope you'll include someday on how to structure the code when start making any program and what are we gonna be using first, would it be an if else statemnt or directly use object instead. Thank you. Much appreciated ❤️

[smallsir]

Thank you Sir!!!! Your 10 things javascript developers should know but probably don't have taken me to another level. I'm so glad i discovered your channel!!!! Recursion have been notoriously hard on me lately, I would appreciate if you can clear me out on it as you have done on other concepts. Lot's of respect from

I just finished writing an app with a C# backend and HTML/CSS/JS front end. I know just enough about JavaScript to understand and copy a few examples I found online. Now, I really want to understand JavaScript, the code I copied and what it really does. I went through a lot of trial and error because I didn't understand stuff. I have watched a couple of your videos and am very impressed. I'm going to watch this series from start to finish and try and understand everything.

After 50 years of software development, I am now retired and I write software, now, just because I enjoy it. I never really have understood JavaScript, so now is my chance. Your presentations are very polished and easy to follow.

[obiajuluanthony]

I respect you a lot, you're a great teacher and trust me ive had a lot of teachers

[devsCafe]

I really loved when you chose Qoli over James or Jack 😂😂

[surajraika]

I am waiting for your video from long time....
You explain very well...

[ferreven]

Walter white indeed does a *different* type of cooking lol

There is a big difference between knowing something and being able to teach something in a way that a learner gets a good fundamental understanding of the concepts of what you are teaching. You have bridged that gap which many experts fail to do. Well DONE !!!

As an intermediate professional programmer I knew all of this already, but I still found this video to be a fun and relaxing refresher on all the topics covered. It's a really great presentation about an important topic that all programmers need to start caring about if they want to start learning more advanced things, and especially if they want to start learning lower level stuff.

[kotik]

just started fullstack coding bootcamp- this is my favorite JS channel i've found!! will recommend to everyone in my cohort. THANK YOU!

[kartikeyshukla]

somehow this video came in my feed. this is really what i needed. Thanks a lot sir!!

[sila-qqku]

Asynchronous programming should definitely be covered next: Promises, Async await the whole concept would be interesting to learn from your perspective.

If you been building the course for years, at the time of this video, and you still ain’t come out with this course, then I’ll definitely been well beyond needing this course. It’ll years before this course is put out. I started learning web development in April of this year, and I followed Coder Coder because her style of teaching really resonated with my learning style. She teaches mainly the basics of HTML, CSS, SCSS, NPM, GIT/GITHUB, and what these people fail to realize, is that there are maybe 500 other teachers and organizations doing exactly what you’re setting out to do. I’m well pass what she can teach me, and I just started learning JavaScript September 1st of this year! I’ll be on React, and React Native by the time this course comes out.

Two topics I would love for you to cover are service workers and web sockets

[davidhaiman]

these are the most engaging/entertaining educational coding videos I've ever watched.

[AbdulazizAliev]

Hi I am Ilkhom. I started learning learning JavaScript two weeks ago. I am really interested in this language. I must admit that these videos really helped to understand JavaScript well as a beginner. Thank you a lot for the awesome and in detail videos.

[yasinnkhann]

I love the effort and quality of these videos!
