Coroutines vs Threads: Which is Better?

What are the main differences between coroutines and threads?

Coroutines are lightweight, cooperative tasks that can pause and resume, while threads are heavier, preemptive tasks managed by the OS.

When should I use coroutines instead of threads?

Use coroutines for I/O-bound tasks where you want to manage concurrency without the overhead of threads. They're great for async programming.

Are there any performance benefits to using coroutines?

Yes, coroutines can be more efficient in terms of memory and CPU usage, especially in applications with many concurrent tasks.

Can you give an example of a situation where threads are preferable?

Threads are preferable in CPU-bound tasks where you need true parallelism, like heavy computations that can benefit from multi-core processors.
