Javascript how to check object is empty or not

In JavaScript everything start with object. Object has vital role while working with JavaScript.

We define object with two curly braces like

const user={};
later can add key value pairs in it like
user.name="User"
user.email="user@gmail.com"

But mostly we have to check that object is empty or not. So let's check it

const user={};

console.log(Object.keys(user).length) // will log 0

user.name="User"
user.email="user@gmail.com"
console.log(Object.keys(user).length) // will log 2
