Angular is a popular web application framework for building dynamic and scalable applications. It comes with built-in support for Reactive Extensions for JavaScript (RxJS), which is a library for composing asynchronous and event-based programs using observable sequences.
In the example above, we create an observable data$ that emits a single value after a delay of 2 seconds. We subscribe to the observable and log the emitted value.
This is just a simple example, but RxJS offers many more powerful operators and concepts such as map, filter, debounceTime, and so on, which allow you to transform and handle streams of data in various ways.I hope this gives you a brief overview of using RxJS with Angular. Feel free to explore the RxJS documentation for more in-depth information and examples.
