Bitwise OR Assignment (|=) Operator in JavaScript (original) (raw)

Last Updated : 19 Jun, 2023

The Bitwise OR Assignment Operator in JavaScriptis represented by (|=). This operator is used to perform a bitwise OR operation on both operands and assign the result to the left operands.

Syntax:

a |= b

Where -

Example 1: In this example, we will use basic numeric values to perform Bitwise OR Assignment Operation.

JavaScript `

let a = 2; // Binary presentation of 10 let b = 3; // Binary presentation of 11 let c = a |= b console.log(c);

`

Output: In this example, the Binary representation of 2 is 10 and the binary representation of 3 is 11. By applying the OR assignment (|=) operation, 3 is returned as the result.

3 // Bit presentation 11

Example 2: In this example, we will use bitwise OR assignment operation to combine the bit values of both numbers.

JavaScript `

let x = 10; // Binary presentation 1010 let y = 12; // Binary presentation 1100

console.log(x|=y);

`

Output: A bit representation of 10 is 1010 and 12 is represented as 1100. by performing OR Assignment(|=) 1110 is returned which contains all the bits of both numbers and returns 14.

14 // Bit presentation 1110
