JavaScript For...of and For...in Loops: A Complete Guide

The for...of loop is used to iterate over iterable objects, such as arrays, strings, maps, sets, and more. It directly provides the values of the iterable.

Syntax:

for (element of iterable) {
    // Code to execute for each element
}

element: A variable that stores the value of the current item in the iteration.
iterable: An object that can be iterated (e.g., an array, string, or other iterable).

Iterating Over an Array

let numbers = [10, 20, 30, 40];

for (let number of numbers) {

console.log(number);

}

Try it yourself

Iterating Over a String

let str = "hello";

for (let char of str) {

console.log(char);

}

Try it yourself
