Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every significant word ("The Quick Brown Fox"). Sentence case capitalises only the first letter of each sentence ("The quick brown fox").
Does Title Case handle small words correctly?
Yes. Articles, conjunctions and short prepositions such as a, an, the, and, or, of and in stay lowercase unless they open or close the title.
Which case should I use for code?
camelCase for JavaScript variables, PascalCase for classes and React components, snake_case for Python and SQL, and kebab-case for CSS classes, URLs and file names.
