What are the 2 categories of Server-side Scripting?

Server-side scripting can be categorized into two main types:

1. Web Template Systems: These are server-side scripting systems that are designed to process web templates and content information to produce output web documents. They are primarily used to separate the design of a website from its content.

2. Web APIs: These are sets of rules and protocols that allow interaction between software applications. In the context of server-side scripting, web APIs are used to enable interaction between the server-side script and the server itself. This can include tasks such as retrieving data from a database, or updating the state of the server.
