<html>    <body>        <form>         <input type="button" value="Click" onclick="show()"/>          </form>       <script src="show.js">       </script>    </body> </html>

On running the above “myfile.js” file, the following is visible. Press the button “Click”:

On clicking above, the following alert is visible which we added in the external file by creating a JavaScript function:
