> The TS compiler might produce something It'll produce calls to React.createElement provided with: the tag name, props, and children. That's all JSX is. > but that's not usually enough in the context of a larger React application (eg, they often import non-ts files) React and JSX don't require you to import non-ts files. If RawJS's nascent ecosystem picks up momentum, people might start importing non-ts files in RawJS projects (e.g. css modules). My point is that there's nothing special about the RawJS api that allows you to skip a build step, and conversely, there's nothing about React that requires Babel (assuming you're already using TypeScript).
