How do I reverse an array in JavaScript in 16 characters or less without .reverse()?

Question

I\'m trying to solve a challenge on Codewars which requires you to reverse an array in JavaScript, in 16 characters or less. Using .reverse() is not an option.

Answer 1

I'd like to give you a hint, without giving you the answer:

You're close, but you can save characters by not using something you need to add in your code.

By adding the thing you won't use, you can remove ().

Spoiler (answer):

// Note: this only really works for this specific case.
// Never EVER use this in a real-life scenario.

var a = [1,2,3,'a','b','c',[]]

weirdReverse=a=>a.sort(x=>1)
//                     ^ That's 1 character shorter than ()

console.log(weirdReverse(a))
