Reverse

The reverse method can be used on any type of array, including arrays of strings, arrays of numbers, and arrays of objects. For example.

let users = [{
  name: "John Smith",
  age: 30
}, {
  name: "Jane Doe",
  age: 25
}];

users.reverse();

console.log(users);

// RESULT: 
[{
  name: "Jane Doe",
  age: 25
}, {
  name: "John Smith",
  age: 30
}];

The reverse method transposes the elements of the calling array object in place, mutating the array, and returning a reference to the array. Here is an example of using reverse of an array:

const numbers = [1, 2, 3];
const newLength = numbers.reverse();
console.log(numbers); // [3, 2, 1]
