Join Creation Operators.

RxJS is a library for composing asynchronous and event-based programs by using observable sequences. It provides one core type, the Observable, satellite types (Observer, Schedulers, Subjects) and operators inspired by Array methods (map, filter, reduce, every, etc) to allow handling asynchronous events as collections.

Think of RxJS as Lodash for events.

ReactiveX combines the Observer pattern with the Iterator pattern and functional programming with collections to fill the need for an ideal way of managing sequences of events.

The essential concepts in RxJS which solve async event management are:

Observable: represents the idea of an invokable collection of future values or events.

Observer: is a collection of callbacks that knows how to listen to values delivered by the Observable.

Subscription: represents the execution of an Observable, is primarily useful for cancelling the execution.

Operators: are pure functions that enable a functional programming style of dealing with collections with operations like map, filter, concat, reduce, etc.

Subject: is equivalent to an EventEmitter, and the only way of multicasting a value or event to multiple Observers.

Schedulers: are centralized dispatchers to control concurrency, allowing us to coordinate when computation happens on e.g. setTimeout or requestAnimationFrame or others.

RxJS Operators

RxJS is mostly useful for its operators, even though the Observable is the foundation. Operators are the essential pieces that allow complex asynchronous code to be easily composed in a declarative manner.

What are operators?

Operators are functions. There are two kinds of operators:

Pipeable Operators are the kind that can be piped to Observables using the syntax observableInstance.pipe(operator()). These include, filter(), and mergeMap(). When called, they do not change the existing Observable instance. Instead, they return a new Observable, whose subscription logic is based on the first Observable.

A Pipeable Operator is a function that takes an Observable as its input and returns another Observable. It is a pure operation: the previous Observable stays unmodified.

A Pipeable Operator is essentially a pure function which takes one Observable as input and generates another Observable as output. Subscribing to the output Observable will also subscribe to the input Observable

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
