kotlinx-coroutines

What problem does it solve?

Writing asynchronous Kotlin code is error-prone when relying on callbacks or manual thread management; this guide consolidates best practices for safe, readable concurrency using coroutines.

Core Features & Use Cases

• Structured concurrency: ensure a parent scope waits for all children, with proper cancellation propagation.
• Suspend functions, dispatchers, cancellation, Flow and StateFlow/SharedFlow for streaming data and reactive UI patterns.
• Testing with runTest and coroutine-aware testing patterns to achieve deterministic time control and reliable assertions.

Quick Start

Create a small Kotlin project and implement a simple coroutine example to practice structured concurrency.
