JavaScript Array reverse() Method

Try it on GfG Practice

The JavaScript Array reverse() method reverses the order of the elements in an array in place. The first array element becomes the last, and the last element becomes the first, and so on.

It modifies the original array and returns a reference to the reversed array. We can also use the Array.toReversed() which returns the new array with the elements in the reverse order.

Syntax:

arr.reverse()

Parameters:

This method does not accept any parameter

Return value:

Returns the reference of the reversed original array.

JavaScript Array reverse() Method Examples

Example 1: Reversing Array Order with JavaScript Array reverse()

The function func() initializes an array arr with elements. It logs the original array, then reverses its order using the reverse() method, storing the result in new_arr, and logs the reversed array.

function func() {
    // Original Array
    let arr = ['Portal', 'Science',
        'Computer', 'GeeksforGeeks'];
    console.log(arr);

    // Reversed array
    let new_arr = arr.reverse();
    console.log(new_arr);
}
func();

[ 'Portal', 'Science', 'Computer', 'GeeksforGeeks' ]
[ 'GeeksforGeeks', 'Computer', 'Science', 'Portal' ]

Example 2: Reversing Array Order with JavaScript Array reverse():

In this example, the reverse() method reverses the sequence of the array elements of arr.

function func() {

    // Original Array
    let arr = [34, 234, 567, 4];
    console.log(arr);

    // Reversed array
    let new_arr = arr.reverse();
    console.log(new_arr);
}
func();

[ 34, 234, 567, 4 ]
[ 4, 567, 234, 34 ]
