Why Case Conventions Matter

Consistent naming conventions make code more readable and maintainable. Different programming languages and contexts use different case styles, and knowing when to use each is essential for writing clean, professional code.

Common Case Conventions

camelCase

Used for: JavaScript variables, functions, object properties Example: userName, calculateTotal, isActive

PascalCase

Used for: Class names, constructors, types Example: UserProfile, DatabaseConnection, ApiClient

snake_case

Used for: Python variables, database columns, file names Example: user_name, calculate_total, is_active

kebab-case

Used for: CSS classes, HTML attributes, URLs, package names Example: user-name, calculate-total, is-active

CONSTANT_CASE

Used for: Constants, environment variables, configuration Example: MAX_RETRIES, API_BASE_URL, DEFAULT_TIMEOUT

Language-Specific Guidelines

JavaScript/TypeScript

  • Variables/Functions: camelCase
  • Classes/Interfaces: PascalCase
  • Constants: CONSTANT_CASE
  • CSS Classes: kebab-case

Python

  • Variables/Functions: snake_case
  • Classes: PascalCase
  • Constants: CONSTANT_CASE

Java

  • Variables/Methods: camelCase
  • Classes: PascalCase
  • Constants: CONSTANT_CASE

  • Consider readability over brevity
  • Document any deviations from standards

Common Mistakes

  • Mixing conventions within the same codebase
  • Using the wrong case for the context
