This codemod removes `React.FC`, `React.FunctionComponent` and `React.SFC` and replaces the Props as the type of the unique argument in the component definition. This codemod supports: - Inline defined props. - Generics. - Props defined with intersection. - Component modules defined using intersection. - Regular named functions. - Functions that accept a component definition. - Using FC, FunctionComponent and SFC as a named export. ## Before: ```jsx type Props2 = { id: number }; export const MyComponent2: React.FC<Props2> = (props) => { return <span>{props.id}</span> } ``` ## After: ```tsx type Props2 = { id: number }; export const MyComponent2 = (props: Props2) => { return <span>{props.id}</span>; }; ```

Transform React components using Material UI JSS APIs (e.g., makeStyles/withStyles/createStyles) into strongly typed `tss-react` hook-based styling (`makeStyles` from `tss-react/mui`) in TypeScript React codebases, improving maintainability and type safety while modernizing legacy styling patterns.
