Loops with Arrays in JavaScript

 let num = [3, 5, 1, 2, 4];

for (let i = 0; i <= num.length; i++) {
    console.log(num[i]);
}

//ForEach Loop in JavaScript
num.forEach((element) => {
    console.log(element * element);
});

//Array.from
let name = "Harry";
let arr = Array.from(name);
console.log(arr);

//for...of
for (let i of num) {
    console.log(i);
}

//for...in
for (let i in num) {
    console.log(num[i]);
}

OUTPUT:
3 5 1 2 4 undefined 9 25 1 4 16 [ 'H', 'a', 'r', 'r', 'y' ] 3 5 1 2 4 3 5 1 2 4
