RxJS
RxJS is one of the popular libraries in web development today. It offers a powerful, functional approach for dealing with events and with integration points into a growing number of frameworks, libraries, and utilities.
With observables we can easily manage asynchronous data streams in React. The Observer and Observable interfaces provide a generalized mechanism for push-based notifications, also known as the observer design pattern. Stated another way RxJS is a set of libraries for composing asynchronous and event-based programs using observable sequences and fluent query operators.
Here are the benefits of using RxJS:
- Greater separation of concerns between component presentation and component logic.
- Component description is more consistent.
- RxJS processes huge data sets in arrays and does not need to organize step-by-step processing of this data, you can use RxJS operators as something like transducers when they process these data sets without creating intermediate arrays.
