How to Use the Array push() Method in JavaScript

In this article, you will learn how to use the array push() method in JavaScript.

The push() method

The push() method is a method for adding one or more elements to the end of an array.
For example, if you add ‘strawberry’ to the array [‘apple’,’orange’,’banana’], it will look like [‘apple’,’orange’,’banana’,’strawberry’].

The syntax is below.

array.push(element0)
array.push(element0,element1)
array.push(element0,element1,...,elementN)

Add elements to the array with push()

Below is a sample to add elements to the array.

const score_a= 80;
const score_b = 90;
const score_c = 70;
// Define an array without data
let scores = [];
// Add elements to the array
scores.push(score_a);
scores.push(score_b);
scores.push(score_c);

console.log(scores);
//[80, 90, 70]

Next, let’s see if we can add the object type to the array.

const score_a = { subject: 'a', score: 80 };
const score_b = { subject: 'b', score: 90 };
const score_c = { subject: 'c', score: 70 };
// Define an array without data
let scores = [];
// Add elements to the array
scores.push(score_a);
scores.push(score_b);
scores.push(score_c);

console.log(scores);
// [
// { subject: 'a', score: 80 },
// { subject: 'b', score: 90 },
// { subject: 'c', score: 70 }
// ]
