Can you name declarative programming languages you are familiar with?

Declarative programming languages describe what needs to be done, not how to do it. They focus on specifying the desired result.

Some well-known declarative languages and technologies:

• SQL — a query language for databases, describing what data is needed, not how to retrieve it.
• HTML — a markup language describing the structure of a web page.
• CSS — describes styles for elements without specifying algorithms for application.
• Prolog — a logic programming language where facts and rules are defined.
• Haskell — a functional programming language with a declarative style.

In the context of Golang, although the language itself is imperative, declarative approaches can be used, for example, in configuration descriptions or declarative UI frameworks.
