camelCase vs PascalCase?
camelCase starts lowercase (firstName) — used for variables and methods in JS, Java, Swift. PascalCase capitalizes the first letter too (FirstName) — used for classes and types.
snake_case vs kebab-case?
snake_case uses underscores (Python, Rust). kebab-case uses hyphens (CSS, URL slugs). They are functionally equivalent for readability.
Why CONSTANT_CASE?
Convention in C/Java/JS for module-level constants and environment variables. Visually distinguishes them from normal variables.
