The three stages of variable naming in every developer's career:
Top: camelCase - One hump for each word. Simple, elegant, industry standard.
Middle: PascalCase - Like camelCase but with an ego. Every word gets to start with a capital letter.
Bottom: snake_case - For when you're slithering through code at 3am and can't be bothered to reach for the shift key.
And somewhere, not pictured: kebab-case - The naming convention that didn't make it into the suitcase.
