How to Push an Object to an Array in JavaScript

Arrays of objects in JavaScript is a powerful feature because of how much information you can store all in one variable.

In this post, we're going to learn how you can push an object to an array in JavaScript.

Pushing an object to an array

When you have an an array of objects and want to push another object to the end of the array, you can use the push() method.

This method takes the object as a parameter and adds it at the end of the array.

First, let's define our array:

JAVASCRIPT
let array = [
    {
        name: 'John',
        age: 30
    },
    {
        name: 'Jane',
        age: 28
    }
];

Now the object we want to push:

JAVASCRIPT
const object = {
    name: 'Bob',
    age: 25
};

Now we can push it and print it:

JAVASCRIPT
array.push(object);

console.log(array);

Here's the full example:

JAVASCRIPT
let array = [
    {
        name: 'John',
        age: 30
    },
    {
        name: 'Jane',
        age: 28
    }
];

const object = {
    name: 'Bob',
    age: 25
};

array.push(object);

console.log(array);

The output is:

JAVASCRIPT
0: {name: 'John', age: 30}
1: {name: 'Jane', age: 28}
2: {name: 'Bob', age: 25}

As expected, our new object is added to the end of the array, making the entire array have a length of 3.

Conclusion

In this post, we looked at how to push an object to an array in JavaScript.

You just need to call the push() method on the array and pass in the object you want to push to the end.
