Text Case Styles
Different naming conventions are used in programming and writing. camelCase and PascalCase are common in JavaScript and TypeScript. snake_case is standard in Python and Ruby. kebab-case is used in CSS and URL slugs. CONSTANT_CASE is used for constants in many languages.
When to Use Each Case
Use Title Case for headings, UPPERCASE for emphasis or constants, Sentence case for regular text, and language-specific conventions (camelCase, snake_case, etc.) for variable and function naming.
