Trip into the async world
summary
Compares RxJava and Coroutines with concrete examples: Retrofit (noting Retrofit 2.5.1 snapshot needed for suspending methods and the later adapter changes), testing differences using runBlockingTest versus RxJava test operators, and the JetBrains bridge with await. Shows a working conversion of an Apollo GraphQL callback into a four-line suspend implementation using suspendCancellableCoroutine. Claims coroutines reduce boilerplate, make testing simpler, and reports a migration from ~3% to ~50% Kotlin in two years on a large codebase.
