Frequently asked questions
camelCase starts with a lowercase letter (myVariableName) and is common for variables and functions in JavaScript. PascalCase capitalizes every word including the first (MyVariableName) and is typically used for class and component names.
This converts the first letter of every word to uppercase and the rest to lowercase. It doesn't apply style-guide exceptions for short words like 'a' or 'the' — for that level of control, tweak the result manually after converting.
Yes — snake_case, kebab-case, camelCase, and PascalCase all split words on existing separators (spaces, hyphens, underscores) or capital letters, so converting an existing identifier between styles works the same as converting a sentence.
