What are the best practices for using async in C++14?

Some best practices include using std::future for asynchronous results, handling exceptions properly, and avoiding shared state.

Can you explain how to handle exceptions in async tasks?

Certainly! You can use std::future's get() method, which will throw any exceptions that occurred in the async task.

What about managing shared resources in async functions?

It's crucial to use synchronization mechanisms like mutexes to avoid data races when accessing shared resources.

Are there any performance considerations I should be aware of?

Yes, be mindful of the overhead of context switching and ensure that your tasks are sufficiently large to justify async.
