What is the Case Converter?

Frequently asked questions
What is Title Case?
Title Case capitalises the first letter of each major word, like a headline: "The Quick Brown Fox".
What is the difference between camelCase and snake_case?
camelCase joins words and capitalises each after the first (userName); snake_case joins them with underscores (user_name).
