What is the TypeScript return type of a React stateless component?

Question

What would the return type be here?

const Foo
  : () => // ???
  = () => (
    

      Foobar
    
  )

Answer 1

I would also add .SFC, which stands for Stateless Functional Component.

const Foo
  : React.SFC<{}>
  = () => (
    

      Foobar
    
  )
