Reactive Programming with Observables in RxJS and Angular
We have seen that now a days reactive programming has changed the whole structure of how we develop our web application. Reactive programming is a programming paradigm that works with asynchronous data streams.It treats everything as a stream ordered in time and this stream can be generated by Http Requests, UI Events or array-like objects etc. RxJS is one of the implementation in javascript of ReactiveX API.These API can be used with many others languages such as Java, C#, Python, PHP, ruby etc. It is a library for composing asynchronous and event-based programs by using observable sequences for reactive programming In this post we will deep dive how RxJS observables are being used with Angular to do reactive programming and different operator which RxJs provides to handle the data well. So Let's start from observables first . What are Observables ? Observables are nothing but a stream of data whose data arrive asynchronously .These data streams can be of anythi
