Deklaratívnych

Deklaratívnych is a Czech word that translates to "declarative" in English. In computer science, a declarative programming paradigm is a style of building the structure and elements of computer programs that expresses the logic of a computation without describing its control flow. This contrasts with imperative programming, which describes how a program operates step-by-step.

Declarative programming focuses on what the program should accomplish rather than how it should accomplish it. This can lead to code that is more concise, easier to understand, and less prone to errors. Examples of declarative languages and paradigms include SQL (Structured Query Language) for database querying, HTML (HyperText Markup Language) for web page structure, and functional programming languages like Haskell.

In SQL, for instance, a user declares what data they want to retrieve, and the database system figures out the most efficient way to get it. Similarly, in HTML, you declare the elements of a web page (like headings, paragraphs, and images), and the browser interprets this declaration to render the page. The emphasis is on the desired outcome or state, not on the sequence of commands to reach that state. This approach often involves abstracting away the underlying implementation details.
