How to Dynamically Include an External JavaScript File

When working with JavaScript, you may find yourself wanting to include external libraries directly into your code. This is common when you’re using libraries like Axios for making HTTP requests, but what if you want to do this without adding <script> tags in your HTML file? Let’s explore how you can achieve this using just JavaScript.

The Challenge: Including External Files
