Get Started with TypeScript - Part 2 - Add a new State type

RocketApp.tsx

import * as React from 'react';
import './styles.css';
// Rocket Info
import { mission } from './data/rockets';
import 'bootstrap/dist/css/bootstrap.css';

// Create a State type below this line
type State = {}

export default class RocketApp extends React.Component<{}, {}> {...}
