Frequently asked questions
What is Title Case?
Title Case capitalizes the first letter of every word, the style commonly used for English headlines and book titles.
What are camelCase, snake_case and kebab-case for?
They are naming styles used in programming: camelCase joins words with capital letters (myVariableName), snake_case uses underscores (my_variable_name) and kebab-case uses hyphens (my-file-name).
Does it work with non-English text?
Yes. Uppercase and lowercase conversion follows Unicode rules, so accented letters and other alphabets convert correctly. Scripts without letter case, such as Korean, remain unchanged.
