我正在尝试学习钩子，但这种useState方法让我感到困惑。我正在以数组的形式为状态分配初始值。无论有没有传播语法， set
方法useState都对我不起作用。

我在另一台 PC 上创建了一个 API，我正在调用它并获取我想要设置为状态的数据。

这是我的代码：

<div id="root"></div>

<script type="text/babel" defer>
// import React, { useState, useEffect } from "react";
// import ReactDOM from "react-dom";
const { useState, useEffect } = React; // web-browser variant

const StateSelector = () => {
  const initialValue = [
    {
      category: "",
      photo: "",
      description: "",
      id: 0,
      name: "",
      rating: 0
    }
  ];

  const [movies, setMovies] = useState(initialValue);

  useEffect(() => {
    (async function() {
      try {
        // const response = await fetch("http://192.168.1.164:5000/movies/display");
        // const json = await response.json();
        // const result = json.data.result;
        const result = [
          {
            category: "cat1",
            description: "desc1",
            id: "1546514491119",
            name: "randomname2",
            photo: null,
            rating: "3"
          },
          {
            category: "cat2",
            description: "desc1",
            id: "1546837819818",
            name: "randomname1",
            rating: "5"
          }
        ];
        console.log("result =", result);
        setMovies(result);
        console.log("movies =", movies);
      } catch (e) {
        console.error(e);
      }
    })();
  }, []);

  return <p>hello</p>;
};

const rootElement = document.getElementById("root");
ReactDOM.render(<StateSelector />, rootElement);
</script>

<script src="https://unpkg.com/@babel/standalone@7/babel.min.js"></script>
<script src="https://unpkg.com/react@17/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom@17/umd/react-dom.production.min.js"></script>

既不setMovies(result)也不setMovies(...result)工作。

我希望将result变量推入movies数组。
