The Atomic object of JavaScript is an object and which provides atomic operations such as add, sub, and, or, xor, load, store etc. as static methods, these methods are used with SharedArrayBuffer objects.The xor() function of the atomic object accepts a number and the position and, performs an xor operation on the given value at the given position.SyntaxIts syntax is as followsAtomics.xor()Example Live Demo JavaScript Example var arrayBuffer = new SharedArrayBuffer(16); var data = new Uint8Array(arrayBuffer); data[0] = 30; document.write(Atomics.xor(data, 0, 3)); document.write(", "+Atomics.load(data, 0)); Output30, 29
