Frequently asked questions

What is camelCase used for?

camelCase and PascalCase are the naming conventions in JavaScript, Java and C#; snake_case is common in Python and databases; kebab-case is the standard for URLs, CSS classes and file names.

Does it handle Chinese or accented characters?

Case transforms work for all Latin-based alphabets. CJK characters have no case and pass through unchanged; mixed text is handled word by word.

Is my text uploaded?
