How to dynamically load external scripts and stylesheets using JavaScript?

To dynamically load external scripts and stylesheets using JavaScript, you can follow these steps:

Create a new <script> or <link> tag element using the document.createElement method.

var script = document.createElement('script');
var link = document.createElement('link');

Set the src attribute for scripts or href attribute for stylesheets to the URL of the external file.

script.src = 'external_script.js';
link.href = 'external_stylesheet.css';

Finally, append the newly created element to the <head> or <body> tag of the HTML document using the appendChild method.

For scripts:

document.head.appendChild(script);

For stylesheets:

document.head.appendChild(link);

Note: It is usually considered best practice to append <script> elements to the <head> tag and <link> elements to the <head> or <body> tag.

By following these steps, your external script or stylesheet will be dynamically loaded into the page.
