Syntax

Operator: x ^= y
Meaning:  x  = x ^ y

Examples

Using bitwise XOR assignment

let a = 5;      // 00000000000000000000000000000101
a ^= 3;         // 00000000000000000000000000000011

console.log(a); // 00000000000000000000000000000110
// 6

let b = 5;      // 00000000000000000000000000000101
b ^= 0;         // 00000000000000000000000000000000

console.log(b); // 00000000000000000000000000000101
// 5
