Programming case styles, explained
Different languages and ecosystems favor different naming conventions: camelCase for JavaScript variables, PascalCase for classes and React components, snake_case in Python and SQL, kebab-case for URLs and CSS, and CONSTANT_CASE for constants. This tool splits your input on spaces, separators, and existing camelCase boundaries, so it round-trips between any of them — all in your browser.
