declaratyvus

Declaratyvus is a term used in computer science and programming to describe a style of programming that focuses on *what* the program should achieve rather than *how* it should achieve it. This is in contrast to imperative programming, which specifies the exact sequence of commands a computer must perform to reach a desired state.

In a declaratyvus paradigm, programmers declare the desired outcome or properties of the computation. The underlying system, be it a compiler, interpreter, or engine, then figures out the most efficient way to satisfy these declarations. This separation of concerns can lead to code that is often more readable, maintainable, and less prone to errors, as the programmer doesn't need to manage low-level details like loop control or memory management.

Examples of declaratyvus programming include SQL for database queries, HTML for web page structure, and configuration languages for setting up software. Functional programming languages like Haskell and Lisp also exhibit strong declaratyvus characteristics. The emphasis is on expressing logic and constraints, allowing the execution environment to optimize performance and handle the procedural execution. This approach can simplify complex systems by abstracting away the intricate steps of computation.
