The Quick Brown Fox. Sentence case only capitalises the first letter of the entire string (or each sentence) — The quick brown fox. Use Title Case for article headlines and book titles; Sentence case for labels, captions, and UI text.getUserProfileData and convert it to Title Case to get Get User Profile Data. It handles camelCase, PascalCase, snake_case, kebab-case, and CONSTANT_CASE as input.myVariableName. It's the standard for variable and function names in JavaScript, Java, and many other languages. PascalCase is the same but with the first letter also capitalised — used for class names and React components.
