Decorator Pattern: Adding Functionality Without Modifying Core Structure

 

The Decorator pattern enables developers to extend the functionality of objects dynamically. Instead of altering the object’s core code, new features can be added at runtime. Shuvo Shahariyer utilizes this pattern to enhance user interfaces or features without disrupting the underlying system. For example, in a text editor application, decorators can be used to add features like spell check or formatting without changing the fundamental text field structure.
