Decorator

A decorator is a design pattern in programming that allows you to add new functionality to an existing object or function dynamically, without changing its original structure. Think of it like attaching accessories to a plain coffee mug—adding a handle or a design—enhancing its features without altering the core object. In code, decorators wrap around functions or objects, extending their behavior in a clean, flexible way. This approach promotes code reuse and helps manage complex features by layering enhancements without cluttering the original code.
