如何使用 Typescript 将 JSON 数据转换为键值对

Question

一个 JSON 数据有 2 个数组（类别和小程序），如下所示。每个小程序根据数据可以属于多个类别。

categories = ['Investments', 'Operations', 'Performance'];

applets = [
  {
    name: 'Performance Snapshot',
    categories: ['Performance'],
  },
  {
    name: 'Commitment Widget',
    categories: ['Investments'],
  },
  {
    name: 'CMS',
    categories: ['Investments', 'Performance'],
  },
];

我需要将该 JSON 数据转换为按类别使用它们，如下所示。如何在 Typescript 中执行此操作？？

categories = [
    {
       'name': 'Performance',
       'applets': ['CMS', 'Performance Snapshot']
    },
    {
        'name' : 'Investments',
        'applets' : ['Commitment Widget', 'CMS']
    },
    {
        'name' : 'Operations',
        'applets' : []
    }
]

Answer 1

    const result = categories.map((category) => {
         const temp = {};
         const filteredApplets = applets.filter((ele) => 
                      ele.categories.includes(category)).map(({name}) => name);
         temp['name'] = category;
         temp['applets'] = filteredApplets;
         return temp;
   })
