How to Dynamically Add Script Tag with document.write in JavaScript

Adding a script tag dynamically with document.write in JavaScript can be a useful technique for loading external scripts and content into your webpages. In order to dynamically add a script tag, you can use the document.write method to write the HTML code for the tag directly into the document.

To do this, you'll need to create a new script element using the createElement method, and then set its type and src attributes to the appropriate values. Once you've done that, you can use the document.write method to write the opening and closing script tags, along with the new script element, directly into the document.

Here's an example of how to dynamically add a script tag using document.write in JavaScript:

var script = document.createElement('script');
script.type = 'text/javascript';
script.src = 'https://example.com/script.js';
document.write('<script type="text/javascript" src="' + script.src + '"></script>');

In this example, we first create a new script element and set its type and src attributes to the appropriate values. We then use document.write to write the opening and closing script tags, along with the new script element, directly into the document. This will load the external script located at the specified URL into the page.

Overall, dynamically adding script tags with document.write in JavaScript can be a powerful technique for loading external scripts and content into your webpages. By using this technique, you can easily and efficiently add new functionality to your site without having to reload the entire page.
