forEach object JavaScript | Example code

  • by

JavaScript forEach() function lets you iterate over an array, but not over an object. If you want to iterate over a JavaScript object using forEach() then first convert an object into an array, using Object.keys(), Object.values(), or Object.entries().

Under ECMAScript 5, you can combine Object.keys() and Array.prototype.forEach():

var obj = {
  first: "John",
  last: "Doe"

Object.keys(obj).forEach(function(key) {
  console.log(key, obj[key]);

Example forEach object JavaScript

Simple example code iterates over each key in the object using forEach() with Object.keys() function.

    const obj = {
      name: 'James Bond',
      rank: '007'

    Object.keys(obj).forEach(key => {
      console.log(key, obj[key]);
