What are some examples of declarative programming?

What are some examples of declarative programming?

Declarative programming focuses on what to achieve rather than how to achieve it. Examples include SQL, HTML, and functional programming languages like Haskell.

Can you explain how SQL is a declarative language?

Sure! In SQL, you specify what data you want to retrieve or manipulate without detailing the steps to get there. For example, a query like 'SELECT * FROM users WHERE age > 30' tells the database what to return without explaining how to do it.

What about HTML? How does it fit into declarative programming?

HTML is declarative because it describes the structure and content of a webpage. You define elements like headings, paragraphs, and links without specifying how the browser should render them.

Are there any other languages that are considered declarative?

Yes, other examples include Prolog, which is used for logic programming, and CSS, which describes how HTML elements should be styled.
