Description: A message handler is a component that processes messages in an application. In the context of programming, especially in event-driven architectures, this type of handler is used to manage communication between different parts of a system, facilitating interaction between software components. Message handlers are fundamental in event-driven architectures, where events generated by the user or the system are captured and processed asynchronously. This allows applications to be more reactive and scalable, as components can operate independently and communicate through messages. Additionally, message handlers can include logic to filter, transform, or route messages to different recipients, increasing the flexibility and maintainability of the code. In various programming languages, message handlers are often implemented using delegates and events, allowing for clearer and more structured programming. In summary, a message handler is essential for creating modern applications that require efficient and effective communication between their components.
