Here is ReactJS project, I've built while studying in a coding camp: github.com/DimaDK24/clever-kid-game
It requires firebase config to launch locally. It should be simple json object in the game/firebaseConfig.json file. Its structure is described in firebase docs: firebase.google.com/docs/web/setup...
BTW, nice idea - post code reviews on YouTube. I definitely will watch some videos!
