Description: The Decorator design pattern is a programming technique that allows for the dynamic addition of behavior to individual functions or methods. This pattern is based on the idea of wrapping an object with another object that adds additional functionalities without modifying the original object’s structure. In the context of programming languages, the Decorator is often implemented as a function that takes another function as an argument and returns a new function that can perform additional tasks before or after the execution of the original function. This approach promotes code reuse and separation of concerns, allowing functions to maintain their simplicity while complex features can be added. Decorators are particularly useful in various development frameworks, where they can be used to manage aspects such as authentication, activity logging, or data validation, providing an elegant and efficient way to extend application functionality without complicating its design.
