What is Title Case?
Title Case capitalizes the first letter of each significant word in a phrase: 'The Quick Brown Fox'. Style guides differ on which small words (a, the, in, on, at, to, for) should remain lowercase unless they start the title. It's used for headlines, book titles, and formal headings. Some modern style guides prefer sentence case for a more conversational feel.
What's the difference between Title Case and Sentence case?
Title Case capitalizes most words: 'The Quick Brown Fox Jumps Over the Lazy Dog'. Sentence case only capitalizes the first word and proper nouns: 'The quick brown fox jumps over the lazy dog'. Sentence case is more readable for longer text and is increasingly preferred for web UI. Title Case is traditional for formal headlines.
When should I use UPPERCASE?
Use UPPERCASE sparingly: for acronyms (NASA, HTTP), constants in code (MAX_VALUE), legal terms (TERMS AND CONDITIONS), or specific design emphasis. Avoid UPPERCASE for body text—it's harder to read (10%+ slower according to studies) and is perceived as shouting in digital communication. For emphasis, consider bold instead.
What is camelCase used for?
camelCase (first word lowercase, subsequent words capitalized: getUserName) is used for variable and function names in JavaScript, Java, and many other languages. It's compact, doesn't require special characters, and distinguishes regular identifiers from class names (which use PascalCase). Most JavaScript style guides mandate camelCase for non-class identifiers.
Why do developers use different naming conventions?
Different conventions serve different purposes: PascalCase marks classes/types (UserService), camelCase marks variables/functions (userService), UPPER_SNAKE_CASE marks constants (MAX_SIZE). These visual distinctions help developers understand code structure at a glance. Language communities also have historical conventions that aid consistency across codebases.
Should URL slugs use hyphens or underscores?
Use hyphens (kebab-case): /blog/my-article-title. Hyphens are URL-safe, SEO-friendly (Google treats hyphens as word separators), and visually clear. Underscores can be mistaken for spaces when URLs are underlined. Spaces become %20 which is ugly and can cause problems. Kebab-case is the web standard for URLs.
