Frequently Asked Questions
What's the difference between camelCase and kebab-case?
camelCase joins words with no separator and capitalizes each word after the first (myVariableName), while kebab-case joins words with hyphens in lowercase (my-variable-name) — both are common naming conventions in programming.
Will Title Case correctly handle small words like 'a' or 'the'?
This converter capitalizes the first letter of every word for simplicity and predictability, rather than applying style-guide exceptions for minor words.
Can I convert code variable names in bulk?
Yes, paste multiple lines and apply snake_case or camelCase — the conversion works across the entire text block at once.
