Ruby Ruby Loops Ruby Loops The Ruby Loop

Again this baffles me. What is wrong with my code?

Where do i go wrong here in this look is it the if statement, the counter being added or the loop itself?

loop.rb 
def repeat(string, times)
  fail "times must be 1 or more" if times < 1
  counter = 0
  loop do
    # YOUR CODE HERE
    repeat("hi", 5)
    counter = counter + 1
    if counter == times
      break
    end
  end
end

You're over complicating it, the way to do it is replace repeat("hi",5) with print(string), you made it call the method inside the method you're trying to call which is why its failing.

Also instead of counter = counter + 1 put counter += 1 which increments counter with the value after += which must be an int not a string so don't do "1" just do 1

You are so close! Nice job. Let's build on that.

The ONLY thing I needed to change to make it work was the repeat and substitute it with puts which prints the string (without a newline) each time it goes through the loop.

def repeat(string, times)
  fail "times must be 1 or more" if times < 1
  counter = 0
  loop do
    # YOUR CODE HERE
    # this line prints the string (once each loop interation)
    # this was the ONLY change you needed.
    puts(string)
    counter = counter + 1
    if counter == times
      break
    end   
  end
end
