declaratiivsed

declaratiivsed is a term that refers to a style of programming or system design where the desired outcome or state is described, rather than the explicit steps to achieve it. In contrast to imperative programming, which focuses on *how* to do something through a sequence of commands, declarative programming focuses on *what* should be done. This means the programmer specifies the end result, and the underlying system, compiler, or interpreter figures out the most efficient way to reach that state.

A key characteristic of declarative programming is its focus on logic and data relationships. Instead of writing loops and conditional statements to manipulate data, a declarative approach often involves defining rules or constraints that the system must satisfy. This can lead to more readable and maintainable code, as the intent of the programmer is often clearer.

Examples of declarative programming paradigms include SQL for database queries, HTML for structuring web pages, and configuration management tools like Ansible or Terraform. In SQL, you declare what data you want to retrieve, not the specific algorithms the database should use to find it. Similarly, HTML describes the structure and content of a webpage, leaving the browser to determine how to render it. This separation of concerns can make systems more robust and adaptable to changes.
