So RxJS observer observes the stream, & responds to it’s notification. The next bottle comes so that he can process it in whatever way he wants.So as an observer, employee get notification as: Imagine an observer as an employee in a factory who is observing the bottle as they are emitted onto a conveyor belt. Imagine a stream as a conveyor belt let’s say in a bottle factory, each bottle being processed one at a time rather than in large batches. It can be thought of as flow of data being processed one at a time rather than in chunks. stream is nothing but a sequence of data elements made available over time. Imagine RxJS as, “Manage the incoming data as it flows through time” i.e. RxJS is a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code.

Since that time, the reactive extension library has been implemented for several other languages including Java(RxJava), Python(RxPy), Ruby(Rx.rb), JavaScript(RxJS). Reactive extensions were originally developed by Microsoft as Rx.Net. Combine data for display, cache data to improve performance and react to the user. RxJS, we leverage patterns to collect data from multiple sources. With Reactive E xtension of Java Script i.e. RxJs is a library that brings the concept of “reactive programming” to the web. This post includes some of the learning from this course as well. Thanks to her as she has explained the terms very well. Hello everyone! In this article I will be talking about RxJS as I have just completed a course from Pluralsight on RxJS in Angular: Reactive Development by the author Deborah Kurata.
