How to Check if an Object is Empty with Javascript

We are all aware that the most popular datatype in programming is the object. There are always situations where you wish to use Javascript to determine whether an object is empty or not.For those who don’t know what is object is basically is so object is a collection of related data stored as key-value pairs. for example :

let userData = {
  name: "ziontutorial",
  username: "zion"
}

In javascript there are many ways to do that or check whether an object is empty or not. In this article, we will be discussing many ways to check whether your object is empty or not.

Note: Always remember if an object has no key-value pair then in that scenario that object is considered as Empty.

Here is a basic example for you:

let userData = {};

Method 1: How to Check if an Object is Empty by Using Object.keys():

if you are looking for a simpler and more concise way to check whether if an object is empty, you can use the Object. keys() method, as it’s quite straightforward. Here’s a simplified version:

function isObjectEmpty(obj) {
  return !Object.keys(obj).length;
}

const myObject = {}; // An empty object
console.log(isObjectEmpty(myObject)); // true

Method 2: How to Check if an Object is Empty by Using JSON.stringify():

You can convert the object to a JSON string using JSON.stringify(), and then check if the resulting string is equal to “{}” for an empty object.

function isObjectEmpty(obj) {
return JSON.stringify(obj) === '{}';
}

const myObject = {}; // An empty object
console.log(isObjectEmpty(myObject)); // true
