Frequently Asked Questions about Case Converter

What is camelCase vs snake_case vs kebab-case?

camelCase removes spaces and capitalizes each word except the first (myVariableName). snake_case joins words with underscores in all lowercase (my_variable_name). kebab-case joins words with hyphens (my-variable-name).

Is my text saved anywhere?

No. Case conversion happens entirely inside your browser's JavaScript engine — nothing is sent to any server.

When should I use PascalCase vs camelCase?

PascalCase capitalizes the first letter of every word including the first (MyComponentName) and is used for class names and React components. camelCase lowercases the first word (myFunctionName) and is the standard for JavaScript variables and function names.
