funniest part of js is the fact that people on stackoverflow CANNOT agree on the best way to make an array of a given length

this is cursed

with ([,,,,,]) { console.log(length) // prints 5 }

thanks I hate it

Sweet merciful Jesus

who dreamed this up

It’s good syntax, lets you do const [,,third, …rest] = arr

we solved that years ago with macros of car and cdr

that's not very zen of python of them

what's the opposite of zen. that's what js has

zen't

there’s a way but the npm package require your firstborn

new Array(42); why

new Array(42).map(() => "hello") // [] new Array({}).map(() => "hello") // ["hello"]

it has 42 empty slots; works as per the spec :) new Array(42).fill('hello');
