Execute Script Asynchronously in HTML

Use the async attribute to set the script to execute asynchronously as and when it is available. It only uses the external script.

Firstly, add a js file. Let us give it a name, new.js,

function sayHello() {
   alert("Hello World")
}

Let’s add the HTML code now and execute the above script −

<html>
   <head>
      <script src = "new.js" ></script>
   </head>
   <body>
      <p>This is demo text.</p>
   </body>
</html>
