# Introduction



Clear examples, explanations, and resources for RxJS.



_By_ [_@btroncone_](https://twitter.com/BTroncone)



## Introduction



[RxJS](https://github.com/ReactiveX/rxjs) is one of the hottest libraries in web

development today. Offering a powerful, functional approach for dealing with

events and with integration points into a growing number of frameworks,

libraries, and utilities, the case for learning Rx has never been more

appealing. Couple this with the ability to utilize your knowledge across

[nearly any language](http://reactivex.io/languages.html), having a solid grasp

on reactive programming and what it can offer seems like a no-brainer.



**But...**



Learning RxJS and reactive programming is

[hard](https://twitter.com/hoss/status/742643506536153088). There's the

multitude of concepts, large API surface, and fundamental shift in mindset from

an

[imperative to declarative style](https://tylermcginnis.com/imperative-vs-declarative-programming/).

This site focuses on making these concepts approachable, the examples clear and

easy to explore, and features references throughout to the best RxJS related

material on the web. The goal is to supplement the

[official docs](http://reactivex.io/rxjs/) and pre-existing learning material

while offering a new, fresh perspective to clear any hurdles and tackle the pain

points. Learning Rx may be difficult but it is certainly worth the effort!

### Brand New to RxJS?



Start getting familiar with all the key concepts needed to be productive with

our [RxJS Primer](/concepts/rxjs-primer.md)!



## Content



#### Operators



Operators are the horse-power behind observables, providing an elegant,

declarative solution to complex asynchronous tasks. This section contains all

[RxJS operators](/operators/README.md), included with clear, executable

examples. Links to additional resources and recipes for each operator are also

provided, when applicable.



##### Operator Categories



- [Combination](/operators/combination/README.md)

- [Conditional](/operators/conditional/README.md)

- [Creation](/operators/creation/README.md)

- [Error Handling](/operators/error_handling/README.md)

- [Multicasting](/operators/multicasting/README.md)

- [Filtering](/operators/filtering/README.md)

- [Transformation](/operators/transformation/README.md)

- [Utility](/operators/utility/README.md)



**OR...**



[Complete listing in alphabetical order](/operators/complete.md)



#### Understanding Subjects



A Subject is a special type of Observable which shares a single execution path

among observers.



- [Overview](/subjects/README.md)

- [AsyncSubject](/subjects/asyncsubject.md)

- [BehaviorSubject](/subjects/behaviorsubject.md)

- [ReplaySubject](/subjects/replaysubject.md)

- [Subject](/subjects/subject.md)



#### Concepts



Without a solid base knowledge of how Observables work behind the scenes, it's

easy for much of RxJS to feel like 'magic'. This section helps solidify the

major concepts needed to feel comfortable with reactive programming and

Observables.

- [Get started transforming streams with map, pluck, and mapTo](/concepts/get-started-transforming.md)

- [Time based operators comparison](/concepts/time-based-operators-comparison.md)

- [RxJS v5 -> v6 Upgrade](/concepts/rxjs5-6.md)
