## What is Reactive Playground?

Reactive Playground is a visual learning app for reactive programming.

Instead of reading operator definitions only, you can play with marble timelines directly. Pick a category, open an operator, move events around, edit their values, clone items, remove them, or turn them into errors and completed events. The output updates live so you can understand what each operator really does.

Explore operator categories such as:

Transforming
Filtering
Combining
Error Handling
Utility

Each playground shows a source timeline, an output timeline, a short explanation, and a code-style example. It is useful for learning ReactiveX concepts, reviewing operators, or quickly refreshing how a stream behaves before using it in code.

Reactive Playground is made for developers, students, and anyone learning Rx-style reactive programming.
