gerrard00 / sort-strings-backwards.js

Last active August 28, 2016 16:56

Sort an array of strings backwards in js...I don't know why

	// an array of strings mangled with this function will sort
	// backwards. You can then mangle them again after the sorting
	// to get your original words. of course, you could just do sort().reverse(), but
	// I was curious. So, completely useless.

	function invertString(input) {
	let result = '';
	for(let c of input) {
	const oldCode = c.codePointAt(0);
