Really nice article!
One thing I was confused about was

invoke bar. bar returns a setTimeout function.
Enter fullscreen mode Exit fullscreen mode

Doesn't setTimeout return an id that you can pass to clearTimeout? 🤔

Yes, It does Jonas, so lets say


let id = setTimeout( () => {
return "hey"}, 1000);

console.log(id) // you will get 1

let id2 = setTimeout( () => {
return "hey"}, 1000);

console.log(id2) // you will get 2
