URL encoding refers to replacing certain characters in a URL with one or more character triplets composed of the percent character '%' followed by two hexadecimal numbers. Because the Web server handles both the resource represented by the URL and the URL itself, it is up to the web server's owner to properly manage that resource and its associated URL. There are several exceptions in practice, the most frequent being a URL linking to a resource that no longer exists or has migrated. These resources include an HTML page, a CSS document, a picture, etc.
Each valid URL, in principle, links to a different resource. A URL is the address of a certain Web site. URL is an abbreviation for Uniform Resource Locator. In this tutorial, we will learn how to decode a URL using JavaScript.
