Description: The event listener pattern is a design pattern that allows objects to subscribe and react to events. This approach is fundamental in modern programming, especially in the development of interactive applications. Essentially, the pattern facilitates communication between different components of an application, allowing one object (the emitter) to notify other objects (the listeners) when a specific event occurs. This is achieved by creating a subscription and notification system, where listeners register to receive updates about events of interest. This pattern promotes a decoupled architecture, meaning that components can evolve independently, improving the maintainability and scalability of the code. The ability to listen and respond to events is essential for creating smooth and engaging user experiences, making the event listener pattern a key tool for developers in various programming environments.
