The following article explains When Should We Use JSTL.

Basically, JSTL (JavaServer Pages Standard Tag Library) provides a convenient way for carrying out important operations in JSP (JavaServer Pages) pages, such as iteration, conditionals, and formatting. In general, you should consider using JSTL when any of the following situations arises.

  • When you want to simplify your JSP pages. JSTL provides a set of tags that can help to reduce the amount of Java code in a JSP page. As a result, the page becomes more maintainable.
  • Likewise, if you want to improve code modularity and maintainability. JSTL tags can help to separate presentation logic from business logic, making it easier to maintain and update your application.
  • Similarly, if you want to provide a standard way to perform usefuk frequently used operations. JSTL provides a standard set of tags that can be used across different web applications, making it easier to share code and collaborate with other developers.
  • When you want to avoid writing custom tags. JSTL provides a set of tags that cover many common tasks, so you don’t need to write custom tags for each application.
  • You want to improve performance. JSTL tags are optimized for performance and can help to improve the performance of your JSP pages.

Overall, JSTL can help to simplify JSP page development and improve code modularity and maintainability. Therefore, by using JSTL tags, you can avoid writing custom tags for each and every operation.
