What’s the difference between Title Case and Capitalized Case?

Title Case follows professional style guides by capitalizing major words while keeping minor words (like “a”, “the”, “and”, “of”) lowercase. Example: “The Quick Brown Fox”

Capitalized Case capitalizes every word without exceptions. Example: “The Quick Brown Fox”

Title Case is better for professional headlines and articles. Capitalized Case is useful for display text and proper names.

When should I use camelCase vs snake_case?

camelCase is standard in:

  • JavaScript, TypeScript
  • Java, C#
  • Variable and function names
  • Example: getUserName

snake_case is standard in:

  • Python, Ruby
  • Database table/column names
  • File names
  • Example: get_user_name

What is CONSTANT_CASE used for?

CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) is the universal standard for:

  • Constants in programming
  • Environment variables
  • Configuration values
  • API keys
  • Example: MAX_CONNECTIONS, API_KEY, DATABASE_URL

What’s the best case format for URLs?

kebab-case is best for URLs because:

  • SEO-friendly (search engines read hyphens as word separators)
  • Readable and clean
  • Web-safe characters
  • Standard for URL slugs and CSS classes
  • Example: best-practices-guide
