Frequently Asked Questions
Title Case capitalizes the first letter of every word: "The Quick Brown Fox Jumps." Sentence case capitalizes only the first letter of the first word and proper nouns: "The quick brown fox jumps." Title case is used for headings, article titles, book titles, and navigation labels. Sentence case is used for body text, email subjects, and most UI labels in modern design systems.
CamelCase writes compound words with no spaces, capitalizing each word except the first: "myVariableName". It is the standard naming convention for variables and functions in JavaScript, Java, C#, Swift, and many other languages. PascalCase (every word capitalized: "MyClassName") is used for class names and components. snake_case (words separated by underscores) is standard in Python and Ruby.
Inconsistent casing causes matching failures in databases and code. "Apple", "apple", and "APPLE" are different strings — a database query for "apple" won't match "Apple" without case normalization. Lowercasing all text before comparing or storing is a fundamental data quality step in any data pipeline, search engine, or user authentication system.
