Where camelCase is used
camelCase is the usual style for variables and functions in JavaScript, Java, and Swift, and for keys in many JSON APIs.
One name per line
Each line is converted separately, so you can paste a whole list at once. Input that is already in snake_case, kebab-case, PascalCase, or CONSTANT_CASE is split into words correctly first.
