What am I doing wrong?

def square_array(array)
  square_bois[]
  counter = 0
    while array[counter] do
    square_bois.push(array[counter]**2)
    counter+=1
    end
    p square_bois
end

Disregarding the missing = after square_bois...

• I should have defined counter and square_bois outside of the while/do loop.
• The info following square_bois.push shouldn't be in () apparently. It worked without them.
• Finally, I needed to call the new array or else it will just be floating in the ether unused and unloved.

Here is the code I ended up with that works:

def square_array(array)
    counter = 0
    square_bois = []

    while array[counter]
    square_bois.push array[counter]**2
    counter+=1
    end
    square_bois
end

numbas= [3, 6, 9]
square_array(numbas)
