Understanding Text Case Conventions

Different programming languages and style guides require different casing conventions. JavaScript uses camelCase for variables, Python prefers snake_case, CSS uses kebab-case, and constants are typically SCREAMING_SNAKE_CASE. Title Case capitalizes the first letter of major words and is used for headings. Sentence case capitalizes only the first word and proper nouns.

Frequently Asked Questions

What is camelCase used for?

camelCase is the standard naming convention for variables and functions in JavaScript, TypeScript, Java, and Swift. The first word is lowercase and subsequent words start with an uppercase letter.

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every major word (articles and prepositions may stay lowercase). Sentence case capitalizes only the first word of each sentence, like normal prose.

Does it work with non-Latin alphabets?

Yes. The converter uses the browser's built-in Unicode-aware casing functions, so Cyrillic, Greek, and other scripts are supported.

Is my text private?

Completely. The conversion happens in your browser using JavaScript. No data is transmitted.
