What are some examples of concurrent programming in Ruby?

In Ruby, you can use threads, fibers, and the Concurrent Ruby gem for concurrent programming. Would you like examples?

Yes, please provide examples using threads.

Sure! Here's a simple example using threads:

threads = []
5.times do |i|
  threads << Thread.new do
    sleep(1)
    puts "Thread #{i} finished"
  end
end

threads.each(&:join)

This creates 5 threads that run concurrently.

What about using the Concurrent Ruby gem?

Using the Concurrent Ruby gem, you can use Concurrent::Future for asynchronous execution. Here's an example:

require 'concurrent'

future = Concurrent::Future.execute { sleep(1); "Result from future" }
puts future.value # This will block until the future is complete.
