camelCase: the standard for JavaScript and JSON
camelCase is the dominant naming convention for variables, functions, and properties in JavaScript, TypeScript, Java, Swift, and many other languages. The first word is fully lowercase; each subsequent word starts with a capital letter. All whitespace and separator characters are removed.
Examples of camelCase in practice:
firstName,lastName,emailAddress— object propertiesgetUserById,handleSubmit,calculateTotal— function namesisLoading,hasError,shouldRender— boolean variablesapiBaseUrl,maxRetryCount— configuration values
The converter accepts input in any format — plain English phrases, snake_case, kebab-case, PascalCase, or mixed delimiters — and produces clean camelCase output. It intelligently splits on word boundaries, including transitions from lowercase to uppercase in existing camelCase or PascalCase input.
