What are the differences between async and threading in Ruby?

In Ruby, threading allows multiple threads to run concurrently, sharing the same memory space, while async programming uses event loops to handle tasks without blocking. This means async can be more efficient for I/O-bound tasks.

Can you give me an example of how to implement async in Ruby?

Sure! You can use the 'async' gem. Here's a simple example:

require 'async'

Async do
  puts 'Starting async task...'
  sleep 1
  puts 'Async task completed!'
end

What about threading? How would that look?

For threading, you can use the 'Thread' class. Here's an example:

thread = Thread.new do
  puts 'Starting thread...'
  sleep 1
  puts 'Thread completed!'
end
thread.join

Which one is better for performance?

It depends on the use case. Async is generally better for I/O-bound tasks, while threading can be more suitable for CPU-bound tasks, but it also introduces complexity with shared state.
