RxJS Foundations 2026 - Learn Modern Reactive Programming

This course features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. In this comprehensive course, you'll dive into the fundamentals of RxJS, starting with setting up your environment and understanding its core principles. You'll explore key concepts like observables, operators, and the relationship between observers and observables, setting a solid foundation for building reactive applications. Through hands-on exercises, you will master essential operators, including map, filter, and error handling strategies, while learning how RxJS can handle asynchronous data streams more efficiently than promises. As the course progresses, you'll venture into advanced topics such as using subjects, combining observables with operators like combineLatest and forkJoin, and implementing debouncing and throttling techniques. This course also emphasizes practical usage by applying the skills learned to real-world projects, allowing you to integrate RxJS into modern web applications. By the end of the course, you will be able to confidently implement RxJS in your applications, handle complex data flows, create custom observables, and apply advanced reactive programming concepts to real-world projects.
