Here is what i tried(how can i do multiple return):

function isEmpty(arr) {
arr = [[], [0, 1], ['a', 'b'], [undefined]]
for (var i = 0; i < arr.length; i++) {
var elem = arr[i]
if (elem == arr[0]) {
return true

You could store the returns in an array/list and return the array/list itself.

let return = [true , false , false , true];
