const shuffle = ([...arr]) => { 
	let m = arr.length; 
	while (m) { 
		const i = Math.floor(Math.random() * m--); 
		[arr[m], arr[i]] = [arr[i], arr[m]];

	return arr;

const foo = [1, 2, 3]; 
shuffle(foo); // [2, 3, 1], foo = [1, 2, 3]
Why is this a comment??? Single line comments aren't supposed to be multiline!
