Converting short URLs to long URLs can be done using JavaScript and libraries like Axios and Fetch.
With Axios, a promise-based HTTP client, you can initiate a GET request and retrieve the full URL from a short link.
Similarly, the Fetch API provides a modern way to make network requests and obtain the final URL after any redirects.
Both methods offer simple approaches to handle URL redirection, with Axios providing additional features like interceptors and JSON data transformation.
