我们使用 filter 返回符合某些条件的所有电影。

对于 filter 的通过条件，我们在所提供的流派数组上使用 every 。

如果在调用它的数组 ( genreList ) 中的所有元素都针对某些条件返回 true，则 every 返回 true。

对于 every 的条件，我们检查电影的类型数组是否包含给定 genreList 数组中的条目。

因此，用英语来说，此代码表示“请给我所有具有在 gentleList 中给出的所有类型的电影”。

const result= [
    {
      "title": "Mad Max: Fury Road",
      "genre": [
        "Action",
        "Adventure",
        "Sci-Fi"
      ]
    },
    {
      "title": "The Hunger Games: Mockingjay Part 1",
      "genre": [
        "Adventure",
        "Thriller"
      ]
    },
    {
      "title": "Jurassic World",
      "genre": [
        "Action",
        "Adventure",
        "Sci-Fi"
      ]
    },
    {
      "title": "Everest",
      "genre": [
        "Drama",
        "Thriller"
      ]
    },
    {
      "title": "Insurgent",
      "genre": [
        "Adventure"
      ]
    },
    {
      "title": "Sicario",
      "genre": [
        "Action",
        "Crime",
        "Drama"
      ]
    }
  ];
  
const moviesByGenres = (moviesList, genreList) => {
  return moviesList.filter((m) => {
    return genreList.every((g) => m.genre.includes(g));
  });
}

// All action movies
console.log(moviesByGenres(result, ["Action"]));

// All action+adventure movies
console.log(moviesByGenres(result, ["Action", "Adventure"]));

使用 Array#filter 选择符合设定条件的相关项目，并使用 Array#map 选择您感兴趣的所选项目的属性。

const result= [ { "title": "Mad Max: Fury Road", "genre": [ "Action", "Adventure", "Sci-Fi" ] }, { "title": "The Hunger Games: Mockingjay Part 1", "genre": [ "Adventure", "Thriller" ] }, { "title": "Jurassic World", "genre": [ "Action", "Adventure", "Sci-Fi" ] }, { "title": "Everest", "genre": [ "Drama", "Thriller" ] }, { "title": "Insurgent", "genre": [ "Adventure" ] }, { "title": "Sicario", "genre": [ "Action", "Crime", "Drama" ] } ],
  
      search = "Sci-Fi";

      newResult = result
      //which items meet the set criteria?
      .filter(({genre}) => genre.includes(search))
      //what about those items am I zeroing in on?
      .map(({title}) => title);

console.log( newResult );

经过反复试验找到了答案

const n = result.filter((curr) => curr['genre'].includes("Action"))
