getInitialState无法在Movies Tutorial中使用

Question

尝试使用电影应用关注React Native教程。 使用iOS或Android一切正常，直到我们尝试将状态引入组件。 本教程不使用ES6类，但Hello World应用程序确实如此，这就是令人困惑的地方。

教程说要添加getInitialState: function() { return { movies: null, }; }, 因为使用ES6类而假设中断，但是使用构造函数似乎也没有用，所以我想知道正确的方法是什么？

教程

constructor(props) {
  super(props);
  this.state = {
    movies: null,
  };
},

ES6等效？

不要在类中的方法之后使用逗号（，）！
