Case Conversion - Camel Snake Kebab

Different programming languages and scenarios have different text formatting requirements. Here are the four most commonly used naming conventions:

• camelCase (lower camel): First word starts lowercase, subsequent words start uppercase. E.g., userName, getUserId. Widely used for variables and functions in JavaScript, Java, TypeScript.
• PascalCase (upper camel): Every word starts with an uppercase letter. E.g., UserService, HttpClient. Commonly used for class names in C#, Java.
• snake_case (snake): All words lowercase, connected by underscores. E.g., user_name, created_at. The dominant style in Python, Ruby, and database field names.
• kebab-case (spinal): All words lowercase, connected by hyphens. E.g., user-name, font-size. Mainly used in HTML attributes, CSS class names, and URL paths.

Mastering the naming conventions of each language community is key to efficient collaboration:

• JavaScript / TypeScript: Variables and functions use camelCase (myVariable), classes and constructors use PascalCase (MyClass).
• Python: Variables and functions use snake_case (my_variable), classes use PascalCase (MyClass), constants use UPPER_SNAKE_CASE (MAX_RETRY).
• Java / C#: Variables and methods use camelCase, classes and interfaces use PascalCase, constants use UPPER_SNAKE_CASE.
• Ruby: Uniformly uses snake_case; symbols end with ? or ! for predicates or destructive methods (e.g., empty?, save!).
• Go: Exported identifiers use PascalCase (uppercase first letter = public), non-exported use lowercase first letter.
• HTML / CSS: Attribute names and CSS custom properties use kebab-case (data-user-id, --primary-color).

Text processing relies entirely on native JavaScript string methods (e.g., .toUpperCase(), .toLowerCase(), regex) ensuring zero data leakage.
