JavaScript Array push() Method

JavaScript Array push() Method is used to add one or more values to the end of the array. This method changes the length of the array by the number of elements added to the array.

Syntax:

arr.push(element0, element1, … , elementN);

Parameters:

Example 1: In this example, we are adding “GeeksforGeeks” to the array.

JavaScript

function func() {
    let arr = ['GFG', 'gfg', 'g4g'];
    // Pushing the element into the array
    arr.push('GeeksforGeeks');
    console.log(arr);
}
func();

Output

[ 'GFG', 'gfg', 'g4g', 'GeeksforGeeks' ]

Example 2: In this example, the function push() adds the numbers to the end of the array.

JavaScript

function func() {
    // Original array
    let arr = [34, 234, 567, 4];

    // Pushing the elements
    console.log(arr.push(23, 45, 56));
    console.log(arr);
}
func();

Output

7
[
  34, 234, 567, 4,
  23,  45,  56
]

Example 3: In this example, the function push() adds the objects to the end of the array.

JavaScript

function func() {
    // Original array
    let arr = [34, 234, 567, 4];

    // Pushing the elements
    console.log(arr.push('jacob', true, 23.45));
    console.log(arr);
