"push()" method returns the length of array instead of array (JavaScript)

Question

I want to make a new array by adding an element to an existing array by "push()" method.

This is the existing array:

let arr = [{label: 1, value: 1}, {label: 2, value: 2}];

This is the element I want to add to the existing array:

{label: 3, value: 3}

So this is the full code with "push()" method:

let arr = [{label: 1, value: 1}, {label: 2, value: 2}];

let newArr = arr.push({label: 3, value: 3});

console.log(newArr); // 3

But push() method returns the length of the new array which is "3" to "newArr" variable. However, what I really want is the actual new array instead of its length for "newArr" variable.

Are there any ways to get the actual new array for "newArr" variable?

Answer 1

First of all, the new keyword has a specified role in javascript, you can't use it as a variable name.

Reserved keywords in javascript.

Secondly, push method works in situ, you don't have to assign it to a new variable. It won't return a new array, but modify the original one.

var arr = [{label: 1, value: 1}, {label:2, value:2}];
    arr.push({label:3, value:3});
    
    console.log(arr);
