Easy question about "class" in Codea

I’m trying to draw 10 balls at random position by using Class, and here’s my code for that:

--In Main 

function setup()

      myBalls=balls()

end

function draw()

      for i=1,10 do

      myBalls:draw()

      end

 end

--In Class balls

balls = class()

function balls:init(x,y,c)

    self.x = x or math.random(0,WIDTH)

    self.y = y or math.random(0,HEIGHT)

    self.c= color(255,0,0)

end

function balls:draw()

    background(40,40,50)

    fill(self.c)

    ellipse(self.x,self.y,100)

end

But it only shows one ball on the screen.
please leave a comment and help me correct my code>_<
Thanks!

try this (you were only creating one ball in setup)

--In Main 

function setup()
      myBalls={}
      for i=1,10 do
          myBalls[i]=balls()
      end
end

function draw()
      background(40,40,50)  --this must be in draw
      for i=1,10 do
          myBalls[i]:draw()
      end
 end

--In Class balls

balls = class()

function balls:init(x,y,c)
    self.x = x or math.random(0,WIDTH)
    self.y = y or math.random(0,HEIGHT)
    self.c= color(255,0,0)
end

function balls:draw()
    fill(self.c)
    ellipse(self.x,self.y,100)
end
