Common Questions
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter and capitalizes each subsequent word (firstName, getUserData). PascalCase capitalizes every word including the first (FirstName, GetUserData). camelCase is typically used for variables and functions; PascalCase for classes and constructors.
When should I use snake_case vs kebab-case?
snake_case (words_separated_by_underscores) is common in Python, Ruby, and database columns. kebab-case (words-separated-by-hyphens) is standard for URLs, CSS classes, and HTML attributes. They're equivalent in purpose but used in different contexts.
What is Title Case vs Sentence case?
Title Case Capitalizes Every Word (used in headlines and titles). Sentence case Capitalizes only the first letter (used in regular text). Title Case makes headings stand out; Sentence case is natural for body text.
What is CONSTANT_CASE used for?
CONSTANT_CASE (or SCREAMING_SNAKE_CASE) uses all uppercase with underscores. It's the standard for constants in most programming languages: MAX_VALUE, API_KEY, HTTP_STATUS_OK. The uppercase indicates the value should never change.
How do I convert variable names between languages?
Paste your variable name and click the target format. For example, convert JavaScript's getUserName (camelCase) to Python's get_user_name (snake_case), or CSS's user-name (kebab-case) to Java's userName (camelCase). The tool handles all common programming naming conventions.
