List out some advantages of using JSP.

Better performance.
The compilation of JSP is done before it is processed by the server which eradicates the need for loading of interpreter and code script each time.
JSP has access to all-powerful enterprises.
Easy to maintain: JSP can be easily managed because we can easily separate our business logic with presentation logic. In Servlet technology, we mix our business logic with the presentation logic.
JSP can also be used in combination with servlets.
