Shifting bits in JavaScript

Imagine I have a numerical value like

let number = 13434235234334;

I'm interested in bit shifting it either to the left or right, for example:

number >> 2 

or

number << 2

However, at a later point, I want to revert back to the original value of the number (assuming I know how many times I shifted it).

Is there a way to retrieve the original value of number after performing the bitwise operations?

Answer №1

The initial value, x, remains unchanged through bit-shifting operations.

let x = 511;
let y = x >> 4;
let z = x << 3;
/*
x = 511
y = 31
z = 4088
*/

To preserve the original value, simply reference x unless it is being reassigned a different value.
