Script Preparation code:
window.arr = [1, "two", 3, "four", 5, {"sixth": 6}, 7, 8, 9, "ten"];
Tests:
for loop
for (let i = 0; i < arr.length; i++) console.log(arr[i]);
forEach
arr.forEach(el => console.log(el));
map
arr.map(el => console.log(el));
while
let i = 0; while (i < arr.length) { console.log(arr[i]); i++; }
