How To Iterate/loop Over JavaScript Objects

How to iterate/loop over JavaScript Objects

In this post we will give you information about How to iterate/loop over JavaScript Objects. Hear we will give you detail about How to iterate/loop over JavaScript ObjectsAnd how to use it also give you demo for it if it is necessary.

we will learn about different ways through iterate/loop over the JavaScript object.

For in Loop

for in loop helps us to get the object keys by using that keys we are outputting the object values.

This below example shows how to iterate over objects by using a for in loop

const obj  = {   name: "onlinecode.org",   age: 7,   location: "web"}for(let key in obj){    console.log(obj.key);}// first iteration obj.name = "onlinecode.org"// second iteration obj.age = 7// third iteration obj.location = "web"

Object.keys method

In es6 we can do it a better way by using Object.keys() method.

Object.keys method takes the object as an argument and it returns back the array of keys.

const obj  = {   name: "onlinecode.org",   age: 7,   location: "web"}const keys = Object.keys(obj);console.log(keys); // ['name','age','location']for(let key of keys){    console.log(obj.key);}

Object.values method

It helps us to get the array of object values instead of object keys.

const obj  = {   name: "onlinecode.org",   age: 7,   location: "web"}const values = Object.keys(obj)console.log(values); // ['onlinecode.org',7,'web']for(value of values){    console.log(value);}

Output:

'onlinecode.org'7'web'
