What type of scripting keeps website code hidden from users, executing it only on the server?

Server-side scripting refers to code that is executed on the server, meaning that it is processed before any content is sent to the user's browser. This type of scripting allows developers to keep the application's logic and data secure since users will not have direct access to the underlying code. Instead, the server generates the necessary HTML, CSS, or other content in response to a user's request and sends it to the browser, ensuring that the server-side code remains hidden from end-users.

This approach is beneficial for various reasons, including protection of sensitive data, improved performance for certain tasks, and the ability to manage dynamic interactions with databases, user sessions, or application logic. Examples of server-side scripting languages include PHP, Python, Ruby, and ASP.NET.

The other types of options are not applicable in this case; client-side scripting runs in the user's browser and is visible to them, while static and dynamic scripting refer to different characteristics of web pages rather than the location of execution. Static scripting creates fixed content, while dynamic scripting generates content that can change based on user interactions or other variables, but both of these could either operate on the client or server side.
