Reactive programming is an important coding style that evolved from the functional programming world. Reactive code is ideal for processing and connecting realtime streaming data. You can use reactive programming to compose streams into pipelines that cleanly model complex logic with non-blocking operations. Java has excellent reactive support, and one of the most popular reactive Java frameworks is Spring WebFlux.
Angular 16 introduces essential tools like DestroyRef and signals, transforming reactivity and lifecycle management, thereby improving code efficiency and future-proofing for versions 17/18.
