• I tried using the @types/react (version 16.9.19) package and had problems.
• I tried using the latest stable version of tsc (version 3.7.5). https://www.npmjs.com/package/typescript

Simple example code:

const ExampleComponent: FC<{}> = () => {
  // some data example
  const data = [{ name: '123' }, { name: '321' }];

  // return React Elements array
  return data.map(t => <div key={t.name}>{t.name}</div>);
};

Throws an error:

TS2322: Type '() => JSX.Element[]' is not assignable to type 'FC<{}>'.   Type 'Element[]' is not assignable to type 'ReactElement<any, string | ((props: any) => ReactElement<any, string | ... | (new (props: any) => Component<any, any, any>)> | null) | (new (props: any) => Component<any, any, any>)>'.
