JavaScript: Tips of the Day

Randomizes the order of the values of an array, returning a new array

Example:

const tips_shuffle = ([...arr]) => {
  let x = arr.length;
  while (x) {
    const i = Math.floor(Math.random() * x--);
    [arr[x], arr[i]] = [arr[i], arr[x]];
  }
  return arr;
};
const foo = [2, 4, 6];
console.log(tips_shuffle(foo));

Output:

[4, 2, 6]
