Reactive programming with RxJS offers a powerful way to handle asynchronous events and data streams. At the heart of RxJS are Observables, which represent these streams, and Operators, which are functions used to manipulate, transform, and manage the data flowing through them.
Operators are chained together using the pipe() method on an Observable. Each operator takes an Observable as input and returns a new Observable, allowing for complex data flows to be built declaratively.
