常见问题

How does Title Case decide which words to capitalize?+
It capitalizes every word except common short words (a, an, and, the, of, in, on, ...). The first word is always capitalized.
Does camelCase preserve numbers?+
Yes. Numbers are kept in place and treated as part of the word that contains them.
