description	To add an element at the beginning of an array we can use the reverse method. It modifies the original array and return the new array length.

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]
