1:06 why don't you just use structuredClone()? Why are you abusing JSON.parse(JSON.stringify()) here?

Thanks for these tricks, have a great day!

Object destructiring is the best thing since sliced bread. Love a bit of `let { prop1, prop2 } = obj`

Null coalescing instead of `||`

The self-invoking functions are called IIFEs I think

[Marcieur]

It is also possible to use the new Set trick with spreading as in const noDuplicates = [...new Set(duplicates)];

[BenjaminAster]

3:18 Use ??, not || here because if the value is zero, false or an empty string you wouldn't want it to fall back to the default.

0:05 just use a real function () {} (not an arrow function) here, then you can use the "this" keyword. So you can just say this.className.

hello sir, your udemy link is not working

What makes the first example a "must know?" It's interesting but doesn't seem very practical, seems like de-structuring for it's own sake. Much easier and more common to use the (e) instead.

turn to javascript frameworks like react and node js
