The reverse() method reverses the order of the elements in an array.

Syntax

a.reverse()

Return value - The reversed array.

Examples

Example 1: Reverse a given string array

var array1 = ['one', 'two', 'three'];
console.log('array1: ', array1);
// expected output: Array ['one', 'two', 'three']

var reversed = array1.reverse(); 
console.log('reversed: ', reversed);
// expected output: Array ['three', 'two', 'one']

/* Careful: reverse is destructive. It also changes
the original array */ 
console.log('array1: ', array1);
// expected output: Array ['three', 'two', 'one']

Example 2: Reversing the integer elements in an array

const a = [1, 2, 3];

console.log(a); // [1, 2, 3]

a.reverse(); 

console.log(a); // [3, 2, 1]
