Most people do not even think about cancellation, but it is extremely important, and both Android and backend developers benefit from Kotlin Coroutines cancellation mechanisms. Let me give you some examples.

Coroutines are incredibly powerful, but their hidden complexities can trip up even experienced developers.

Kotlin Coroutines provide special support to interoperate with Java, Swift and JavaScript. Thanks to that, calling suspending functions is a breeze.

Many devs start using technology without understanding it first. That is fine, but some technologies give fake confidence, and devs misuse it without even realizing it. Let me use Kotlin Coroutines as a case study. Thread 👇🧵

Testability is one of the most important advantages of Kotlin Coroutines. It supports operating in virtual time, which lets us write precise, fast, and deterministic tests for cases that are hard to test with other libraries. You can easily check any scenario and assert how much time it would take.

Are you also annoyed by the fact that capitalize was deprecated and the replacement is crazy long? I am, but why did it actually happen?
