RxJS (Reactive Extensions for JavaScript) is a very powerful library for web development which allows you to easily write asynchronous or call-back code.

In this course, you will explore the latest version of RxJS in detail, focusing on how to apply the reactive paradigm to solve your day-to-day tasks. You will learn all the major components of this library including: subjects, operators, and how to test observables.

In the last section of this course, you will get hands-on with this library to create your own project. Throughout this project, you’ll learn about building a centralized loading indicator, how to handle DOM events, how to build a reactive local database, and more.

By the end of this course, you will have a great new skill to add to your resume, and a cool new project for your portfolio.

Building Reactive Applications with RxJS

In this course, you were introduced to the *reactive paradigm*, its main components, and its applications. You learned how to apply the reactive programming principles to some real-world applications, and you can easily use that knowledge to apply the reactive paradigm to your own applications, without being bound to the tech stack you are using.

I would like to thank you for being part of this journey, and I certainly hope you enjoyed it. The reactive ecosystem is huge, and as a next step, you can try experimenting on your own by digging deeper into the RxJS documentation, and of course, start using it in your projects right away.

Take care.
