Simple For Loop
// index 0 1 2 3 4
let arr = [23, 12, 53, 34, 54];
for (var i = 0; i < arr.length; i++) {
console.log("arr =", [i], arr[i]);
}
Output
arr = [ 0 ] 23
arr = [ 1 ] 12
arr = [ 2 ] 53
arr = [ 3 ] 34
arr = [ 4 ] 54
Simple While Loop
// index 0 1 2 3 4
let arr = [23, 12, 53, 34, 54];
let j = 0;
while (j < arr.length) {
console.log("arr =", [j], arr[j]);
j++;
}
Output
arr = [ 0 ] 23
arr = [ 1 ] 12
arr = [ 2 ] 53
arr = [ 3 ] 34
arr = [ 4 ] 54
Simple Do While loop
// index 0 1 2 3 4
let arr = [23, 12, 53, 34, 54];
let j = 0;
do {

j++;
} while (j < arr.length);
Output
arr = [ 0 ] 23
arr = [ 1 ] 12
arr = [ 2 ] 53
arr = [ 3 ] 34
