What is the bitwise NOT (~) operator in JavaScript?

Question

Aryan Kumar · Answer

The bitwise NOT (~) operator in JavaScript is a unary operator that's used to invert the bits of a number. It works by changing each 0 bit to 1, and each 1 bit to 0. It's often used to flip the binary representation of a number.

Here's how you can use the bitwise NOT operator in JavaScript:

let num = 5; // Binary representation: 00000101
let invertedNum = ~num; // Binary representation: 11111010

console.log(invertedNum); // Output: -6

In the example above, the ~num operation flips the bits of the number 5 to give you -6 as the result. Just keep in mind that the result is a signed 32-bit integer in two's complement representation, so it may appear as a negative number in some cases.
