Put the code to draw your emoji inside a function. Use x and y as parameter. Draw at least 3 emojis on your canvas.

Advanced exercise
Change your function to also use the background color of your emoji as parameter. Now change the background-color of your emojis on your canvas and create a Warhol style image.
