In the past 20ish months I have watched a lot of people on Youtube doing tutorials and found a lot of amazing people, who I owe a lot to when it comes to me progressing as a programmer. In the past 2 months or so, that i found you though, I am having leaps of progress, especially when it comes to TS and React and also as in this series, vanilla JS. You are really a gem and a true inspiration and invaluable for the community. Your style of teaching is so efficient yet calm and comforting, it has to be the ultimate level of beeing a teacher! Thank you so much for everything and PLEASE PLEASE keep up the good work! Love from Berlin, Germany!

People are loving this content and how you break it down. A big thank you. I just solved my first Algoexpert interview question on my own after studying this series.

Thanks for this great video! To write the code and then also visually explain it with a drawing helps a lot of developers to clarify their understanding. I'm glad that you are filling up your channel with some basic JS fundamentals. Your channel is highly recommended to anyone from beginners to experts! Also, the extension, Quokka, is a great extension to use with your videos! Well done!

[sagarreddy]

As usual awesome content. Please make similar in depth videos on js objects, functions, closure etc. Thanks Mr. Jack

[victorlongon]

Nice content as usual. The most overlooked methods I see are some, every and (to a lesser extend) includes. You can get a very long way using only built in methods. I don't use util libs anymore for a lot of stuff I reached for something like lodash in the past.

From now and on I will just like videos first and then watch :D, Nothing I dislike in this channel, You Sir is exactly what the JS/TS community needs. Thanks for everything you do.

[jaideepsarkar]

Great, Request you to give more in-depth contents on nested Objects and complex data iterations.
it will be gratefull.
love u Jack

It would be amazing to have you as a mentor.
If I had the money, I would probably try to hire you as a personal teacher.
BUT, since I just graduated my re-education as a backend developer, and (still) unemployed, I will just have to keep on following your videos.

Thank you for the effort. Really appreciate it.

[BezzantSam]

The reference aspect was great to learn.

[lowweichieh]

Hi Jack, may I know what is the VSCode extension that you use to show result besides the line of code?

[whatever]

Thank you!. You are absolutely great teacher!.

Amazing, good content and straight to the point.

[footstepparecords]

Thanks a lot! I’m always struggling with arrays😅

[pavanh]

Hey man, How you are getting the output in front of code lines. Which extension are you using for that.

[kicba]

Thank you 👌 What is this addon green square left and log right?

[odalisvalencia]

Buen video, Saludos desde Colombia, ;)

Do you know anything about the array.find method's standard implementation? Ive read that it's just a basic linear search and shouldn't be used for anything other than trivial searches.

Remix is out, so i expect a video on it soon, I hope

Hi jack, another way to mutate a copy whitout change the original value is destructuring the inner object : copy[0] = {…copy[0], name: ‘jack’ }
