Using the Atomics.xor(typedArray, index, value) method

Again, Atomics.xor method performs a bitwise XOR operation, which is an exclusive OR (that is, it is an OR gate which gives 0 when both inputs are 1)

const sab = new SharedArrayBuffer(1);const arr = new Uint8Array(sab);arr[0] = 5; // 5 is 0101 in binary.Atomics.xor(arr, 0, 12); // 10 is 1100 in binaryconsole.log(Atomics.load(arr, 0));

Atomics.xor here performed a XOR operation between arr[0] and the number 10.

This outputs:
