Programming case styles

Different languages use different conventions: JavaScript uses camelCase for variables, PascalCase for classes. Python uses snake_case. Rust uses kebab-case for crate names + CONSTANT_CASE for constants.

When converting between languages or refactoring code, you need to switch cases fast — this tool saves time.

FAQ

What about Vietnamese diacritics?

The tool preserves diacritics (e.g. 'Tên Biến' → 'tenBien' since JS toLowerCase handles diacritics specially). Best to strip diacritics first if you need ASCII.

Are digits preserved in names?

Yes. 'myVar2' → 'my_var_2' (snake), 'my-var-2' (kebab).
