Title Case, Sentence Case & UPPERCASE Rules: Proper case capitalization improves readability across published articles, blog headers, and executive emails. Title Case automatically capitalizes major words while keeping minor prepositions and articles lowercase (following Chicago, APA, or MLA conventions). Sentence Case capitalizes only the first letter of each sentence, ideal for body text formatting.
CamelCase, PascalCase, snake_case & kebab-case: Software developers rely on strict identifier naming conventions: camelCase (used in JavaScript & Java variables), PascalCase (used in React components & C# classes), snake_case (standard in Python & database schemas), and kebab-case (preferred for CSS classes and clean URL slugs).
