useState设置方法不能立即反映更改

我正在尝试学习钩子，该useState方法使我感到困惑。我正在将初始值分配给数组形式的状态。useState即使使用spread(...)或，in中的set方法对我也不起作用without spread operator。我在另一台PC上创建了一个API，该API正在调用并获取要设置为状态的数据。

这是我的代码：

import React, { useState, useEffect } from "react";
import ReactDOM from "react-dom";

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);
        setMovies(result);
        console.log(movies);
      } catch (e) {
        console.error(e);
      }
    })();
  }, []);

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

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

　　

setMovies(result)以及setMovies(...result)不工作。可以在这里使用一些帮助。

我希望将结果变量推入movies数组中。
