Reactive programming is a popular new programming paradigm that makes it easy to code apps and interfaces that respond to dynamically changing data. Now reactive programming has come to JavaScript thanks to the RxJS library. 

RxJS provides an API for asynchronous programming, using entities called "observables" to store data of any type. View components or other objects can then subscribe to observables to react to changing data.

In our new Coffee Break Course, Reactive Programming With RxJS, Envato Tuts+ instructor Reggie Dawson will give you a first look at RxJS. He'll go through some simple examples to show you how the RxJS library works and how to manipulate data using it.

If you haven’t tried one of our Coffee Break Courses before, they’re ultra-short video courses designed to teach a skill or concept in a single sitting. This one is less than ten minutes long, and by the end of it you’ll have a solid understanding of how to use the RxJS library.

Watch the introduction below to find out more.

You can take our new Coffee Break Course straight away with a free 10-day trial of our monthly subscription. If you decide to continue, it costs just $15 a month, and you’ll get unlimited access to our library of hundreds of courses, with new ones added every week.
