What are the differences between async and thread pool in programming?

What are the differences between async and thread pool in programming?

Async programming allows tasks to run concurrently without blocking, while thread pools manage a fixed number of threads for tasks.

Can you explain how async programming improves performance?

Async programming improves performance by allowing other tasks to run while waiting for I/O operations, reducing idle time.

When should I use a thread pool instead of async?

Use a thread pool for CPU-bound tasks where you need to manage multiple threads efficiently, while async is better for I/O-bound tasks.

Are there any downsides to using async?

Yes, async can introduce complexity in code and may lead to callback hell if not managed properly.
