Description: Custom JSP Tags are components developed by programmers to encapsulate reusable functionality in JSP (JavaServer Pages). These tags allow developers to create user interface elements and business logic that can be used across multiple pages, thus promoting modularity and code maintainability. By using custom tags, code writing can be simplified, as it avoids the repetition of logic and improves the readability of JSP pages. These tags are defined in XML files or Java classes and can include attributes that allow customization of their behavior. Additionally, their use contributes to the separation of presentation logic and business logic, which is fundamental in web application development. In terms of performance, custom tags can optimize page loading by reducing the amount of code that needs to be processed on each request, resulting in faster response times and a better experience for the end user.
