Javascript

JavaScript is a scripting language belonging to the network, which has been widely used in Web application development. It is often used to add a variety of dynamic functions to web pages and provide users with a more smooth and beautiful browsing effect.

ASP, namely Active Server Pages, is a server-side scripting environment developed by Microsoft, which can be used to create dynamic interactive web pages and build powerful web applications.

JavaScript, on the other hand, has limited access to HTTP headers and cannot perform any action on the server side (because it runs on the visitor's browser).

However, it can respond to and interact with user actions on a web page generated by the server (the server tells the browser what options the user can use and what to do in response to the user's actions).

Javascript is more limited, but it provides tools to extend the behavior of web pages when the server finishes processing and loses control of it. The basic function of verification.
