How to use Bitwise NOT operator in Javascript

Description

The bitwise NOT is represented by a tilde (~) and returns the one's complement of the number.

Example

var num1 = 25;             //binary 00000000000000000000000000011001
var num2 = ~num1;          //binary 11111111111111111111111111100110
console.log(num2);               //-26

The code above generates the following result.
