Frequently Asked Questions
Title Case capitalizes the first letter of every major word (e.g., "The Quick Brown Fox"). Sentence case capitalizes only the first word of each sentence (e.g., "The quick brown fox"). Title Case is used for headings and titles; Sentence case is standard for regular prose.
camelCase writes compound words with no spaces, capitalizing each word after the first (e.g., "myVariableName"). It's the standard naming convention in JavaScript, Java, and Swift for variables and function names.
