Frequently Asked Questions
- What is the difference between camelCase and PascalCase?
- camelCase starts lowercase (myVariable); PascalCase starts uppercase (MyVariable). JavaScript and TypeScript use camelCase for variables and functions, and PascalCase for classes, React components, and interfaces.
- How does this converter split my input into words?
- It splits on spaces, hyphens, and underscores, lowercases the first word, and capitalizes the first letter of each following word — so "user profile data", "user-profile-data", and "user_profile_data" all become userProfileData.
- How does camelCase compare to snake_case and kebab-case?
- Same words, different separators and capitalization: camelCase (userProfile) has no separator and capitalizes internal words; snake_case (user_profile) joins with underscores, all lowercase; kebab-case (user-profile) joins with hyphens, all lowercase. Use the Snake Case Converter or Kebab Case Converter to convert straight to those instead.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
