### shuffle Randomizes the order of the values of an array, returning a new array. Uses the [Fisher-Yates algorithm](https://github.com/30-seconds/30-seconds-of-code#shuffle) to reorder the elements of the array. ```js 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; }; ``` ```js const foo = [1, 2, 3]; shuffle(foo); // [2,3,1], foo = [1,2,3] ```
