This tutorial should start with the need for set and map in Javascript and also it should cover the differences between set and weakset as well as map and weakmap

I wish you used a bit more time explaining why the following is necessary in the first place. Which holes does these new implementation fill. You don't show anything new with the following video, that I couldn't do with normal object - which is the reason people are watching, after all.

Im a subscriber and I have gained some insight from your videos, thanks a lot for that. However, for this very video, it would have been better if you explained why Set and Map should be used and what problems they solve.
Also, nothing was said about the fact that Set takes unique values, so a repetition of values in the set are ignored.

Hi! I wonder, what is the purpose for using this set and map instead of regular arrays and objects ?

Why don't you explain uses for each one, I guess the syntax it's clearly explained but what is the difference between weakMap and Map, for example?

I don't understand why this video got so many views. It just shows how to use maps and weakMaps, sets and weakSets, but not when to use them as opposed to regular arrays and objects, and also it doesn't say anything about the actual difference between the weak and non-weak versions....

I came here to find out if you could add two of the same values to a set. There was no explicit explanation of this so i just went to the mozilla documentation because its faster and more up to date than every video on youtube

I am getting WeakMap { <items unknown> } and WeakSet { <items unknown> } printed even after inserting items via the respective functions. Please advise.

Can not explain here - What are WeakSet and WeakMap? This video is not helpful.
