Frequently Asked Questions
What is Title Case?
Title Case capitalizes the first letter of every word. For example, "the quick brown fox" becomes "The Quick Brown Fox". It is standard for book titles, article headings, and proper nouns.
What is camelCase and when is it used?
camelCase joins words without spaces — the first word is all lowercase and each subsequent word starts with a capital letter. Example: "my variable name" → myVariableName. It is the standard naming convention in JavaScript, Java, Swift, and many other languages.
What is the difference between snake_case and kebab-case?
Both use lowercase words separated by a delimiter. snake_case uses underscores and is common in Python, Ruby, and SQL. kebab-case uses hyphens and is the standard for URLs, CSS class names, and HTML data attributes.
What is Sentence case?
Sentence case capitalizes only the first letter of the first word in each sentence, plus any proper nouns. It mirrors normal written English and is commonly used in body text, subtitles, and UI labels.
