Kotlin Coroutines mantığı nedir?

It feels a bit like switching from assembly to JavaScript when you move from RxJava or raw thread pools to Kotlin Coroutines—suddenly the compiler is doing the heavy lifting instead of you. Most of the magic isn’t the language feature itself, but the fact that `suspend` functions don’t block threads. Each coroutine is just a lightweight state machine that can be suspended/resumed without locking an actual OS thread, so one small fixed-size dispatcher (the default is usually the JVM’s common pool) can juggle thousands of concurrent tasks without melting your RAM. Compare that to RxJava where you still have to wire up schedulers manually and risk thread leaks if you forget to `subscribeOn`/`observeOn`, or raw Java `ExecutorService` where you’re constantly fine-tuning thread counts and queue sizes. It’s not that coroutines invent something entirely new; it’s more about blurring the line between blocking synchronous code and asynchronous hell so your brain doesn’t spin its wheels on plumbing.
