Decorators: Enhancing Code Functionality and Readability
Decorators represent a powerful and elegant way to modify or enhance functions or methods in programming. At a high level, they are a form of metaprogramming where one function takes another function and extends the behavior of the latter function without explicitly modifying it. This approach promotes cleaner code, reusability, and the separation of concerns, allowing developers to add functionality like logging, access control, or instrumentation to existing code in a declarative and maintainable fashion.
