Frequently asked questions

What's the difference between camelCase and Title Case?

Title Case keeps spaces between capitalized words ("My Variable Name"); camelCase removes spaces and capitalizes every word except the first ("myVariableName") — common in JavaScript variable naming.

How does Sentence case decide where sentences start?

It capitalizes the first letter of the text and the first letter after each period, question mark, or exclamation mark.

Does this handle accented or non-English characters?

Uppercase and lowercase conversion works for most Unicode letters via the browser's built-in case conversion. Word-boundary styles (Title, camel, snake, kebab) are tuned for space-separated words.
