t = Thread.new do  
10.times do |i|  
puts i  
end  
end

10.times do  
puts “!”  
end

#Wait for t to complete  
t.join

I don’t want to go into details about how to do it, I just want to let  
you know it is possible.

Seriously, if you want serious help you need to give a little more  
context. People can try and guess, but why? What are trying to do?  
Iterate over two enumerables simultaneously? Wait for two conditions  
to be met in a specific order?

I’ve been coming across posts about iterating over multiple objects at  
the same time. I can’t recall but i just googled and this one came out  
…
