What are the differences between async and threading in Ruby?

What are the differences between async and threading in Ruby?

In Ruby, async programming allows tasks to run concurrently without blocking, while threading creates multiple threads that can run in parallel.

Can you give me an example of when to use async over threading?

Use async when you have I/O-bound tasks, like web requests, where you want to handle multiple operations without waiting.

What about CPU-bound tasks? Should I use threading for those?

Yes, for CPU-bound tasks, threading can be beneficial as it allows you to utilize multiple cores, but be mindful of Ruby's GIL.

Are there any libraries in Ruby that support async programming?

Yes, libraries like EventMachine and Async provide robust support for async programming in Ruby.
