How to check an object is empty in javascript

As a programmer, we need to handle objects in our daily life.So there should be some cases where we have to check the given object is empty.Empty objects mean there is no keys  for that object.In this blog post I am going to explain How we can easily identify an object is empty or not in javascript

let obj1 ={}

console.log(Object.keys(obj1));    // []

if(Object.keys(obj1).length === 0)

{

    console.log("obj1 is an empty object")

}else{

    

    console.log("obj1 is not an empty object")

}   // obj1 is an empty object

let obj2 ={  name : "Technursery" , visitors : 1000}

console.log(Object.keys(obj2));  // [ 'name', 'visitors' ]

if(Object.keys(obj2).length === 0)

{

    console.log("obj2 is an empty object")

}else{

    

    console.log("obj2 is not an empty object")

}  //obj2 is not an empty object

In the above code, I created two objects obj1 and obj2. obj1 is an object which has no key. So we got an empty array  for keys  and result is obj1 is an empty object .But obj2 is an object which has two keys. So we got an array with two keys as shown in the above code.So obj2 is not an empty object
