What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (e.g., myVariableName), while PascalCase starts with an uppercase letter (e.g., MyClassName). In JavaScript/TypeScript, camelCase is typically used for variables and functions, while PascalCase is used for classes and React components.
When should I use snake_case?
snake_case is commonly used in Python, Ruby, and Rust for variable and function names. It is also widely used for database column names and file names. Words are separated by underscores for readability.
Where is kebab-case used?
kebab-case is used for URL slugs, CSS class names, HTML attributes, and npm package names. Words are separated by hyphens (-), and it is recommended for creating SEO-friendly URLs.
