JSP and JavaScript

Today, I saw some people say JavaScript as JSP. I have already read this situation several times. Why is it so understandable? I am wrong and mislead others.

Below are JSP and JavaScript
JSP is a dynamic web page technical standard proposed by Sun Microsystems and jointly established by many companies. Add Java to traditional webpage HTML files (*. htm, *. html)ProgramSnippets (scriptlet) and JSP tags constitute JSP web pages (*. jsp ). When the Web server encounters a request to access the JSP webpage, it first executes the program fragment and then returns the execution result to the customer in HTML format. Program snippets can operate databases, redirect webpages, and send emails. This is the function required to build a dynamic website. All program operations are performed on the server, and the results are only obtained after the network is uploaded to the client. The client has the lowest requirements on the client browser and can implement no plugin, no ActiveX, and no Java applet, no frame.

Javascript is a descriptive language that can be embedded into HTML files. Javascript can be used to respond to user requirement events (such as form input), so that when a user inputs an item of information, it does not need to be transmitted to the server through the network for processing and then transmitted back, but can directly process events on the client.
