I was so surprised, since I had learned the other way first that it is actually easier to teach functional approaches with teenagers.
arr.map(x => x2) was abundantly clearer than
const newArr = [] for(let i, i < arr.length, i++) { newArr.push(arr[i]2) }
And to be perfectly honest, I might have goofed the for loop.
Yeah, you did! It should have used semi-colons. (And HN has lost the carets …)
And I agree completely with you.

You did, the commas must be semicolons :)
I can't tell you how much time I spent chasing a bug when it was a date that was passed by reference.
Rather than trying to keep track, I just return copies of arrays and objects and it's way easier.
Even a simple
``` function yeppers(input) => ({...input, x: 7}) ```
(An overly simple example)
has made things smoother.
Ok… it’s Footgun prone and callback hell is real.
But I still try to obtain that in other more boring language.
