Description: Protocol extension is a technique used in programming that allows adding functionality to existing protocols without the need to modify their original implementation. This practice is especially common in several modern programming languages where methods and properties can be added to already defined classes, structures, or enumerations. Protocol extension enables developers to enhance code reuse and modularity, facilitating the creation of cleaner and more maintainable applications. Additionally, it promotes separation of concerns, as related functionalities can be grouped into specific extensions, improving code readability. This technique also allows the implementation of common behaviors across different data types, resulting in more efficient and less error-prone code. In summary, protocol extension is a powerful tool in modern programming that helps developers create more flexible and scalable solutions.
