I have to say, Joy's teaching style is completely off the charts. I loved the moment you picked up the keyboard to show where the back tick symbol is located. LOL. Best Javasript Callback, Promises and Async tutorial I have ever encountered. Someone give this man a medal

[tamasve]

I watched this tutorial two times.
How many times?
Two times!

Joy: "we gonna use arrow function"
Joy: "what function?"
Me: "arrrrow funnnnction"

Honestly, this guy is probably one of the greatest teachers i've watched on Youtube. He explains it like we're children, its awesome . Thanks for getting him on your channel

[hassansyed]

Just in the first 13 minutes, I understood more Async than the tutorial I'm watching on Udemy.
Good work my dude

[Misfittykitty]

He took us so patiently through a full seven levels of callback hell, I don't think I'll ever forget it lol! I love this guy's teaching style...Joy, you are the BEST thank you so much. :) :)

[jonasulrych]

I like how lively this teacher is. I didn't get bored a single time throughout the video.

[alexanderfrost]

Such a good teacher. No wonder his name is "Joy" ....he is a real Joy to watch and learn from.

Asynchronous programming is the heart and soul of JS programming. You can't do anything non trivial or call an API without it.

[gime]

The fact you took us through callback hell to point out how mush async/await and promises improved on asynchronous programming is 10/10. Great stuff!

Best teacher on YouTube. No offense to everyone else. This was the first tutorial I have watched where a concept was taught step by step, without copy and pasting, and free of any unnecessary programing concepts or tech. Thank you so much!

[CyberIllusions]

This is by far the best explanation I have seen so far. And I have to say that I have consumed many tutorials that leave you even more confused after the explanation because some things are just very abstract.

Joy has an absolute talent for demystifying these abstractions and explaining them with simple real world analogies so that really EVERYONE can understand. So for JavaScript beginners, absolutely perfect and totally recommended!

Someone once said: if you can't explain something in simple terms, you haven't really understood it yourself. Joy has proven that he understood it. I wish many would follow this example. Big thumbs up for this one!! 👍👍👌👌

"Take the money and buy ourselves a Lambo, because why not " I'm dying. But also thanks for the effort, great, clear video. FINALLY IT MAKES SENSE.

[Web-Dev-Codi]

His teaching ability is something else. Wow, good job!!

[nileshsaini]

Came here for Async js. Going back with a business idea, going to sell ice cream and buy a Lambo : )

[taishienglish]

Ive been studying html, css, and js for about a year now and this was the first video i thought that i could maximine my time with. The hour and a half on this video while doing what he does in code pen solidified the things that I've learned and beyond. Thank for giving us even the slightest hope Joy, you really are one of the best instructors on youtube, I really hope you get the recognition you deserve man.

[shivarapolu]

Beautifully explained. Absolutely loved this, I realised that after taking a paid course this video is better than many paid courses out there and which I took. 🔥🔥🙌

[falytom]

I love how he talks back to us and asks us to repeat after him like we are there with him. He should really be celebrated. His joy for teaching is the best i have ever seen.

[mbulelopani]

😂The way he looks at the camera is like when an intelligent person looks at someone they know is less intelligent and tries to be understanding. Anyway, Joy is brilliant.

[andrnexus]

This is one of the best courses on this subject I have seen. This instructor's energy and references make understanding so much easier! Thank you for doing this course.
