This channel deserves more views, I see all of this garbage tutorials, where for 20 min they say nothing, but get 100k views, because they farmed more subs

Hey brother! Thank you so much 🙂 👍

There's one important detail missing, WeakMaps allow for garbage collection, meaning if a key is no longer in use it will be, well, garbage collected. This is the main use case since Maps aren't subject to garbage collection.

Hey dev dreamer. I have one question, If i have many buttons that performs same function onclick, then how do I select those all buttons in one variable? those buttons have their own ID.

[@DevDreamer]

Hey Bikrant, thank you for watching 🙂 You want to give each of those buttons the same class name, and then use getElementsByClassName:
let x = document.getElementsByClassName("example");
