The bitwise XOR assignment (^=) operator performs bitwise XOR on the two operands and assigns the result to the left operand.
Syntax
x ^= y
Description
x ^= y is equivalent to x = x ^ y, except that the expression x is only evaluated once.
Examples
Using bitwise XOR assignment
let a = 5; // (00000000000000000000000000000101)
a ^= 3; // (00000000000000000000000000000011)
console.log(a); // 6 (00000000000000000000000000000110)
let b = 5; // (00000000000000000000000000000101)
b ^= 0; // (00000000000000000000000000000000)
console.log(b); // 5 (00000000000000000000000000000101)
let c = 5n;
c ^= 3n;
console.log(c); // 6n
