Help with Game States

[RagedElimanator]

Hello there, I have 3 files for a phaser game an html, cs and javascript file(excluding phaser.js). I would really appreciate if someone who understands the this.blank format would help me convert to a game where I have a boot state, menu state and play state of the game. I honestly don't know how to do this, this would help me learn more and also help progress me a bit because I haven't been able to successfully transit into this.blank format although I have been given examples which I would say are way more complicated than my game and those examples were missing some parts that would have helped me that I couldn't find.

code.js

index.html

style.css
