Frequently Asked Questions (FAQ)
camelCase starts with a lowercase letter and capitalizes each subsequent word (e.g. myVariable). PascalCase capitalizes every word including the first (e.g. MyVariable). camelCase is common for variables; PascalCase for class names.
Uppercase and lowercase apply to Latin characters. For non-Latin scripts like Japanese, only any embedded Latin characters are converted.
