How to Append Element to Array in JavaScript

Written by Rahul K.

The push() method is used to add elements in JavaScript array. This tutorial will help you to initialize an array in JavaScript. After that append some more elements in Array using push() method in JavaScript.

Append Element to Array in JavaScript

First, create an array in JavaScript. For example, we are creating an array games with two elements “chess” and “football”.

var games = ['chess', 'football'];

1	var games = ['chess', 'football'];

Now append two more elements “tennis” an “pool” in games array using push() method. This method returns the number of element in array after adding new elements.

var total = games.push('tennis', 'pool');

1	var total = games.push('tennis', 'pool');

Finally you can print the elements of array using console.log() function. You can also check the number of elements by printing total variable value.

console.log(games); // ["chess", "football", "tennis", "pool"]
console.log(total); // 4

1 2	console.log(games); // ["chess", "football", "tennis", "pool"] console.log(total); // 4
