First word lowercase, subsequent words capitalized, no spaces. The standard naming convention for JavaScript variables, object properties, and method names. Improves code readability while remaining compatible with all programming languages.
Examples: "helloWorld", "getUserData", "isActiveUser", "productPrice"
All words capitalized with no spaces between them. Standard naming convention for class names, component names, and type definitions. Used across C#, Java, Python, and JavaScript React components for clear visual distinction of special identifiers.
Examples: "HelloWorld", "UserProfile", "ApiResponse", "DataProcessor"
Words separated by underscores, all lowercase. The preferred naming convention in Python, databases, and backend programming. Standard for SQL column names, Unix file systems, and highly readable in technical contexts.
Examples: "hello_world", "user_name", "database_connection", "api_endpoint"
