Here's why:
* Declarative programming is a programming paradigm, a way of thinking about how to solve problems. It focuses on *what* you want to achieve, rather than *how* to achieve it.
* Symbols are often used for specific syntax elements within a programming language, like operators, keywords, or data types.
Examples of how declarative concepts are represented:
* Functional languages: Use higher-order functions and recursion to express logic in a declarative way.
* SQL: Declarative language used to query data. You specify what data you want, not how to find it.
* CSS: Used to describe the style of web pages, specifying what you want the appearance to be, not how to achieve it.
In short, there isn't a single symbol for declarative programming. It's a broad concept that is implemented in various ways across different languages and systems.
