Kotlin Coroutines

Coroutines give Kotlin a clean way to write asynchronous code without callback nesting. They are common in Android and backend services.

Suspend functions

suspend fun loadUser(): String = "Ada"

Structured concurrency

Use scopes to keep async work organized. The goal is predictable cancellation and easier error handling.

Async flow

Coroutines work well for I/O, parallel waits, and layered service code where the control flow should still read like ordinary code.

Practice

  1. Write one suspend function stub.
  2. Explain why structured concurrency matters in production systems.
  3. Write one note about where coroutines fit better than raw threads.
