Execute Script After Page Parsing in HTML

Use the defer attribute to execute the script when the page has finished parsing in HTML.

Firstly, add a js file.

Let us give it a name, new.js,

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

Example

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

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