How can I return something early from a block?

Question

If I wanted to do something like this:

collection.each do |i|
   return nil if i == 3

   ..many lines of code here..
end

How would I get t

Answer 1

In this instance, you can use break to terminate the loop early:

collection.each do |i|
  break if i == 3
  ...many lines
end

...of course, this is assuming that you're not actually looking to return a value, just break out of the block.
