Example
Following is the code for implementing JavaScript Atomics −
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Atomics Example</title>
<style>
.result {
font-size: 20px;
border: 1px solid black;
}
</style>
</head>
<body onLoad="operate();">
<h1>JavaScript Atomics Properties</h1>
<div class="result"></div>
<p>Atomics.add(arr, 0, 2)</p>
<p>Atomics.load(arr, 0)</p>
<script>
function operate(){
let container = document.querySelector(".result");
// create a SharedArrayBuffer
var buffer = new SharedArrayBuffer(25);
var arr = new Uint8Array(buffer);
// Initialise element at zeroth position of array with 6
arr[0] = 6;
container.innerHTML = Atomics.add(arr, 0, 2) + '<br/>' + Atomics.load(arr, 0);
}
</script>
</body>
