Description: A ‘Subscriber’ is an entity that registers to receive notifications or data from a publisher in the context of programming, especially in TypeScript. This design pattern is based on the publish-subscribe architecture, where the subscriber is interested in certain events or state changes and subscribes to receive updates. In TypeScript, subscribers are essential for implementing reactivity in applications, allowing different parts of a system to communicate efficiently and with loose coupling. Subscribers can be functions, objects, or classes that implement specific methods to handle the notifications they receive. This approach not only enhances code modularity but also facilitates event management in complex applications, such as those developed in real-time communication environments, where responsiveness is crucial. The ability of a subscriber to react to changes in the state of the publisher enables the creation of dynamic user interfaces and systems that respond quickly to user interactions or external events.
