JavaScript Array push() Method

The 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: This method contains as many numbers of parameters as the number of elements to be inserted into the array. 

Return value: This method returns the new length of the array after inserting the arguments into the array. 

Below is an example of the Array push() method.

Example 1:

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:

34,234,567,4,23,45,56

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

    // Original array
