Frequently asked questions

What's the difference between Title Case and Capitalized Case?

Title Case (AP-style) keeps short words like "a", "the", "of" lowercase except at the start. Capitalized Case capitalizes every word regardless.

How does camelCase handle existing camelCase input?

The tokeniser detects word boundaries at case changes (e.g. "XMLHttpRequest" → x m l http request) and rejoins per the target case.

Is there a CONSTANT_CASE variant?

Yes — also known as SCREAMING_SNAKE_CASE. Common for environment variables and language constants.
