Answer 1

import React, {lazy, Suspense} from 'react';
const OtherComponent = lazy(() => import('./OtherComponent'));

function MyComponent() {
  return (
    <Suspense fallback={<Fallback />}>
      <OtherComponent />
    </Suspense>
  );
}

function Fallback() {
  // debug it here to your heart's content
  // same thing with "OtherComponent", debug it in component
  return <div>Loading...</div>;
}
