react/packages/babel-plugin-react-jsx

This package is intended to eventually replace the current @babel/plugin-transform-react-jsx, changing the JSX transform from targeting React.createElement(type, props, children) to React.jsx(types, props, key).

This is experimental and not intended to be used directly.
