why my loop do statement is not working

I am at the part where I need to Add numbers to an array until the number of items in the array are greater than 3. I found the right answer but I am curious why my answer does not work:

loop.rb 
numbers = []

number = 0

loop do
  number = number + 1
  numbers.push(number)
  if numbers.count > 3
    break
  end
end

Hi Matthew,

You may want to use numbers.size to check if the array is equal to 3. If the array size is 3 then the break statement inside the if-statement will be executed.

loop do
  number = number + 1
  numbers.push(number)
  if numbers.size == 3
    break
  end
end

If you have any further questions feel free to ask! Hope this helps!
