Frequently Asked Questions
What case formats does this tool support?
UPPERCASE (all caps), lowercase (all lower), Sentence case (first letter capitalised, rest lower), Title Case (first letter of each major word capitalised), camelCase (first word lower, subsequent words capitalised, no spaces), and PascalCase (all words capitalised, no spaces).
What is camelCase used for?
camelCase is the standard naming convention for variables and functions in JavaScript, TypeScript, Java, and many other languages. Example: 'getUserProfile', 'isLoggedIn', 'totalCartValue'. It distinguishes from snake_case (Python) and kebab-case (CSS/HTML).
When should I use Title Case?
Title Case is standard for blog post titles, article headlines, book titles, and product names in English. The rule: capitalise all words except short prepositions (in, on, at), articles (a, an, the), and conjunctions (and, but, or) unless they're the first or last word.
