Frequently Asked Questions

What are the rules for title case?

Capitalise the first and last words and all major words; leave articles, coordinating conjunctions and short prepositions lowercase in the middle. "The Rise of the Machines", not "The Rise Of The Machines".

What is the difference between camelCase and PascalCase?

Only the first letter. camelCase starts lowercase (userName) and is conventional for JavaScript variables; PascalCase starts uppercase (UserName) and is conventional for class and component names.

When would I use snake_case or kebab-case?

snake_case for Python variables, SQL columns and many config formats. kebab-case for URLs, CSS class names and HTML attributes, since those cannot contain underscores comfortably.

Does it work with accented and non-Latin text?

Yes. Case conversion uses Unicode rules, so accented Latin, Greek and Cyrillic convert correctly. Scripts without letter case, such as Chinese and Arabic, pass through unchanged.
