camelCase starts with a lowercase letter and capitalizes the first letter of each subsequent word. It is commonly used for variable and function names in JavaScript, Java, and many other languages. Example: userProfileSettings

PascalCase (also called UpperCamelCase) capitalizes the first letter of every word, including the first. It is commonly used for class names and component names. Example: UserProfileSettings

snake_case uses lowercase letters with underscores between words. It is commonly used in Python, Ruby, and database column names. Example: user_profile_settings

kebab-case uses lowercase letters with hyphens between words. It is commonly used in URLs, CSS class names, and file names. Example: user-profile-settings

What is CONSTANT_CASE?

CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) uses uppercase letters with underscores. It is used for constants and environment variables. Example: USER_PROFILE_SETTINGS

Title Case capitalizes the first letter of major words while keeping minor words (like "the", "and", "of") lowercase unless they start the title. Example: The Quick Brown Fox

What is Sentence case?

Sentence case capitalizes only the first letter of the first word and proper nouns, like a regular sentence. Example: The quick brown fox jumps.
