What case style should I use for different programming contexts?

Different programming languages and frameworks have established conventions: camelCase (first word lowercase, subsequent words capitalized: myVariableName) is standard for JavaScript, TypeScript, and Java variables/methods. PascalCase (all words capitalized: MyClassName) is used for class names in most OOP languages and React component names. snake_case (all lowercase, underscore-separated: my_variable_name) is the Python standard (PEP 8) for variables, functions, and file names; also common in Ruby, Rust, and SQL column names. kebab-case (all lowercase, hyphen-separated: my-component-name) is used in CSS class names, HTML attributes, and URL slugs. CONSTANT_CASE (all uppercase, underscore-separated: MAX_RETRY_COUNT) is for constants and environment variables across most languages. Title Case (capitalize each word) is for headings, titles, and proper nouns. Using consistent casing within a codebase improves readability and helps linters catch naming convention violations.
