JavaScript Atomics Reference

Atomics is an object in JavaScript that provides atomic operations to be performed as static methods Just like the Math object in JavaScript, all the properties and methods of Atomics are also static Atomics are used with SharedArrayBuffer (generic fixed-length binary data buffer) objects Atomics are not constructors like other global objects Atomics cannot be used with a new operator or can be invoked as a function

Syntax:

Atomicsmethod(argument 1, argument 2, )

Example: In this example load() function of the Atomic object returns the value at a given position of an array

// creating a SharedArrayBuffer
let buf = new SharedArrayBuffer(25);
let arr = new Uint8Array(buf);

// Initialising element at the zeroth 
//position of an array with 9
arr[0] = 9;

// Displaying the SharedArrayBuffer
console.log(Atomics.load(arr, 0));

Output:

9
