About Case Styles

Case styles (or naming conventions) are standardized formats for writing identifiers in programming. Different languages, frameworks, and style guides often have specific preferences for how variables, functions, classes, and other identifiers should be named. Using consistent case styles improves code readability and maintainability.

Common Use Cases

Code Migration: Converting between language conventions
API Integration: Matching external API naming styles
Database Mapping: Converting between DB and code conventions
Style Guide Compliance: Enforcing consistent naming
Framework Requirements: Meeting specific framework conventions

Tips

Be consistent within your codebase
Follow language/framework conventions
Use meaningful and descriptive names
Consider readability and maintainability
Document any deviations from standards

Common Case Styles

camelCase: First word lowercase, subsequent words capitalized. Example: myVariableName. Used in: JavaScript, Java, TypeScript
PascalCase: All words start with capital letter. Example: MyClassName. Used in: C#, TypeScript (classes)
snake_case: All lowercase words separated by underscores. Example: my_variable_name. Used in: Python, Ruby
kebab-case: All lowercase words separated by hyphens. Example: my-component-name. Used in: CSS, HTML attributes
CONSTANT_CASE: All uppercase words separated by underscores. Example: MAX_BUFFER_SIZE. Used for: Constants, environment variables

Language-Specific Conventions

JavaScript/TypeScript: camelCase for variables/functions, PascalCase for classes
Python: snake_case for most identifiers, PascalCase for classes
Ruby: snake_case for methods/variables, PascalCase for classes/modules
Java: camelCase for methods/variables, PascalCase for classes
CSS: kebab-case for class names and properties

Special Considerations

Handle acronyms consistently (e.g., XMLHttpRequest vs XmlHttpRequest)
Consider case sensitivity in different environments
Be aware of language-specific restrictions
Think about international character support
Consider automated tools for enforcement
