  )

Answer 1

interface ISomeCoolInterface {
   some: 'string';
   cool: 'string';
   props: 'string' 
}    

const SomeCoolComponent
    : React.FC 
    = ({ some, cool, props }): JSX.Element => {
        return {some, cool, props}      
    }

The important bit here being the return type JSX.Element
