PascalCase Converter

In short PascalCase, also called UpperCamelCase, joins words with no separator and capitalises every word including the first, so "user profile card" becomes UserProfileCard. It is the convention for class names in almost every object-oriented language, for React and Vue component names, for TypeScript types and interfaces, and for C# public members. The difference from camelCase is exactly one character — the first letter — and most codebases use both, reserving PascalCase for things that are types and camelCase for things that are values. In React the distinction is not stylistic but functional: JSX treats a lowercase tag as an HTML element and a capitalised one as a component, so writing `<myButton />` silently renders an unknown HTML tag while `<MyButton />` renders your component. That is the single most common cause of a React component rendering as nothing at all. Acronyms are the usual awkward case; the common convention is to treat them as ordinary words, giving HtmlParser rather than HTMLParser.
