JavaScript Array.reverse() Method is used for the in-place reversal of the array. This method reverses the order of the array. The first element of the array becomes the last element and the last one becomes the first. It mutates the original 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: This method returns the reference of the reversed original array.
Example 1: The below examples illustrate the JavaScript Array reverse() Method
JavaScript
function func() { // Original Array let arr = [ 'Portal' , 'Science' , 'Computer' , 'neveropen' ]; console.log(arr); // Reversed array let new_arr = arr.reverse(); console.log(new_arr); } func(); |
[ 'Portal', 'Science', 'Computer', 'neveropen' ] [ 'neveropen', 'Computer', 'Science', 'Portal' ]
Example 2: In this example, the reverse() method reverses the sequence of the array elements of arr.
JavaScript
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 ]
