indexOfAll
Returns all indices of val in an array. If val never occurs, returns [].
Use Array.reduce() to loop over elements and store indices for matching elements.
Return the array of indices.
const indexOfAll = (arr, val) =>
arr.reduce((acc, el, i) => (el === val ? [...acc, i] : acc), []);
indexOfAll([1, 2, 3, 1, 2, 3], 1); // [0,3]
indexOfAll([1, 2, 3], 4); // []
