Shift array to right in JavaScript

Question

Below is the array I have: 

var arr1 = ['a1', 'a2', 'a3', 'a4', 'a5'];

I can do a left shift by 2 on it. Can anyone tell me how to perform the right shift by 2 on the array?

Answer 1

You do shift right on N positions and shift left on array.length - N positions. If you want to shift right by 2, you need to shift the array by 3 on the left position.
