What Is a camelCase Converter?
camelCase sits next to snake_case (Python, SQL), kebab-case (URLs, CSS) and PascalCase (class names) in the family of programming naming conventions. It dominates variable names, function names and object keys in JavaScript and TypeScript codebases. The lowercase first letter signals "instance or value," reserving PascalCase for constructors and types.
The converter strips non-letter characters, splits on whitespace and punctuation, lowercases the first segment, and capitalises every subsequent segment's first letter. "User First Name" becomes "userFirstName"; "hello-world" becomes "helloWorld".
For class and type names, use the PascalCase tool instead. For environment variables, use CONSTANT_CASE.
