How Do Coroutines Enhance Multithreading in Android and JVM? 🤔

The animation below 🎥 illustrates how coroutines optimize thread resource utilization for more efficient request processing.

In the first scenario, the thread is blocked until Task 1 is fully completed. It cannot take on any additional tasks, even though it remains idle while waiting for a server response. 😴

In contrast, the second thread can process two requests concurrently because the tasks it handles use coroutines. Here, the coroutine running Task 1 suspends, freeing the underlying thread to process other tasks or coroutines in the meantime. ⚡

This is the power of coroutines—they make multithreading significantly more efficient. 🚀

Threads come with substantial overhead. Even modern computers can only handle a few thousand threads simultaneously. However, they can effortlessly manage millions of coroutines at the same time. 💪
