I just found about codefights.com. It’s an interesting concept, I was able to sign up with this and give it a try. Felt a bit like codecademy.com, which is also an amazing website about learning code. But codefight.com has 2 modes, 1. Solo and 2. CodeFight. This makes it interesting and a bit unique. Also, they have an achievement and point system that makes it feel like a game.
