Frequently Asked Questions
What's the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter (myVariableName), while PascalCase starts with an uppercase letter (MyClassName). camelCase is commonly used for variables and functions in JavaScript/TypeScript, while PascalCase is used for class names and React components.
When should I use snake_case vs kebab-case?
Use snake_case for Python variables, database column names, and file names in certain contexts. Use kebab-case for URLs, CSS class names, HTML attributes, and file names in web development. Both are lowercase with separators, but snake_case uses underscores while kebab-case uses hyphens.
What is CONSTANT_CASE used for?
CONSTANT_CASE (all uppercase with underscores) is the standard convention for naming constants and environment variables in most programming languages. Examples include API_KEY, MAX_RETRIES, DATABASE_URL. It makes constants easily identifiable in code.
Can I convert multiple texts at once?
The tool processes your input text and displays all 9 case formats simultaneously, allowing you to copy any format with one click. For batch processing multiple separate texts, you'll need to process them individually.
