Bootcamp Notes – Day 18 (Sat) – Classwork Assignment – Color Game
Our class worked on this Color Guessing Game. I added a few things to mine to spice it up. Some things were heard to understand. I have decided to get a tutor before it gets really hard later. Anyway you can see my code here and at codepen.io.
