Bitwise XOR assignment (^=)

The bitwise XOR assignment operator (^=) uses the binary representation of both operands, does a bitwise XOR operation on them and assigns the result to the variable.

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

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

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

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

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