Course Summary
The Reactive Programming with RxJS training course teaches students how RxJS is quickly becoming one of the most important libraries in the Javascript toolbox for both Node.JS and front-end JS developers.
The course begins by introducing reactive programming, explaining the observer pattern, subscribing to observable objects, and a deep dive into observables and subjects. Next, through a mixture of short lectures, ample exercises, and labs, students will discover what reactive programming is, why it is beneficial, and how to implement it into their daily practice. The course concludes with students learning about operators and how to combine them, as well as best practices and building reactive components with RxJS.
This course covers all of the essential features of RxJS, including Observables, Subjects, operators, and how to implement reactive programming in your applications.
- Productivity Objectives:
- Describe reactive programming and observables.
- Identify operators and pipe several of them together to produce the right output.
- Exercise subjects to emit data to several subscribers.
