RxMarbles

RxMarbles is an open-source interactive web application that teaches reactive programming through animated marble diagrams. It visualizes how ReactiveX operators transform sequences of events over time. Each diagram displays input streams, operator behavior, and resulting output streams. Users can drag individual marbles along a timeline to observe how different event positions affect the results. The application includes examples of operators used for mapping, filtering, combining, and delaying observable sequences. Individual diagrams can be shared through direct links for demonstrations or educational discussions. Built using Cycle.js, it also serves as an example of reactive interface development. The repository is archived, but the educational website remains accessible.
