Great article! Picked up some tricks that I wish I knew before...

I always found confusing or misleading the syntax for assigning new variable names in object destructuring. Using : inside an object takes my mind to property assignment from right to left, not new variable assignment from left to right. Also, it is too similar to Typescript's type declaration:

const num: int = 5;

And fairly different (and less verbose than) using new variable names in import object destructuring:

import { Component as Comp} from "React";

Rest in Object Destructuring: [ERROR]

var person = {name: "Sarah", country: "Nigeria", job: "Developer" friends: ["Annie", "Becky"]};
Something missing comma between, "Developer" and friends.
Nice article, thx!

Huh, got stuck on Javascript courses about Destructuring, but your post is really clear and will surely help me to defeat the evil forces of those exercices.

Thanks !
