Using loop and break to complete a method

The repeat method should take a string, and print it a specified number of times. Use loop and break to complete the method. Be sure to do the following:

After printing the value of string, add 1 to the counter variable.

Use an if statement together with the break keyword to break out of the loop once counter is equal to times.

The error I get is 'unexpected keyword_end'

loop.rb
def repeat(string, times)
  fail "times must be 1 or more" if times < 1
  counter = 0
  loop do
    print string
    counter += 1
    if counter == times
    break
  end
end

Hi there Richard Wentford! You're super close here, and that's not exactly the error I get when I run your code. This is the error I receive:

Bummer: SyntaxError: f42c40ed-01a5-4c1f-b24b-fd11e17558e3.rb:15: syntax error, unexpected end-of-input, expecting keyword_end

It's expecting another end. There should be an "end" for your function, an "end" for your loop, and an "end" for your if statement making the total number of "end"s three. But you only have two. When I add an extra end to the bottom of your code, it passes with flying colors!

Hope this helps! :sparkles:
