Observable

An Observable is a concept from programming that represents a data stream which can emit multiple values over time. Think of it like a broadcast station that sends out updates—such as new messages, sensor readings, or user actions—allowing other parts of a program to subscribe and react whenever new data arrives. This approach simplifies handling asynchronous events and continuous data flows, making programs more responsive and easier to manage. In essence, Observables help efficiently manage real-time or ongoing data changes in a clear and structured way.
