break and return in ruby, how do you use them?

Question

I just asked a question about return and it seems to do the same thing as break. How do you use return, and how do you use break, such as in the actual code that you write t

Answer 1

I wanted to edit the approved answer to simplify the example, but my edit was rejected with suggestion of making new answer. So this is my simplified version:

def testing(target, method)
  (1..3).each do |x|
    (1..3).each do |y|
     print x*y
     if x*y == target
       break if method == "break"
       return if method == "return"
     end
    end 
  end
end

we can see the difference trying:

testing(3, "break")
testing(3, "return")

Results of first (break statement exiting innermost loop only when 3 reached):

1232463

Results of last (return statement exiting whole function):

123
