Bitwise Operators

Bitwise operators perform operations on the binary representations of numbers. They treat their operands as a sequence of 32 bits (zeroes and ones) and return standard JavaScript numerical values.

Types of Bitwise Operators

• AND (&): Sets each bit to 1 if both bits are 1.
• OR (|): Sets each bit to 1 if one of two bits is 1.
• XOR (^): Sets each bit to 1 if only one of two bits is 1.
• NOT (~): Inverts all the bits.
• Left Shift (<<)< /strong>: Shifts bits to the left, filling with zeros.
• Right Shift (>>): Shifts bits to the right, preserving the sign bit.
• Zero-fill Right Shift (>>>): Shifts bits to the right, filling with zeros.

let a = 5; // 0101
let b = 1; // 0001
console.log(a & b); // 0001 (1)

let a = 5; // 0101
let b = 1; // 0001
console.log(a | b); // 0101 (5)

let a = 5; // 0101
let b = 1; // 0001
console.log(a ^ b); // 0100 (4)

let a = 5; // 0101
console.log(~a); // 1010 (-6)

let a = 5; // 0101
console.log(a >> 1); // 0010 (2)

let a = 5; // 0101
console.log(a >>> 1); // 0010 (2)
