push to object javascript

push to object javascript

When working with JavaScript, the push() method is used to add one or more elements to the end of an array. It modifies the array in place and returns the new length of the array.

The syntax for the push() method is as follows:

array.push(element1, ..., elementN);

Where element1, ..., elementN are the elements to be added to the end of the array.

For example, to add an element to the end of an array, we can use the following code:

let numbers = [1, 2, 3]
// numbers is now [1, 2, 3, 4]

We can also add multiple elements to the end of an array at once:

let numbers = [1, 2, 3]
numbers.push(4, 5, 6);
// numbers is now [1, 2, 3, 4, 5, 6]

The push() method is often used to add new elements to an array, such as when we need to store data in an array. For example, we could use the push() method to add an object containing user data to an array:

let users = [];

let user = {
  name: 'John',
  age: 30


The push() method is an essential part of working with arrays in JavaScript, and understanding how it works and how to use it is an important part of becoming a proficient JavaScript developer.
