javascript - 将源 JSON 字符串合并到具有相似键但在 javascript 中具有不同结构的目标

Question

我有两个 JSON 字符串，如下所示:

source = [
  {
    "name": "test1",
    "values": ["User Support"],
    "enabled": false
  },
  {
    "name": "test2",
    "values": ["M"],
    "enabled": true
  },
  {
    "name": "test3",
    "values": ["CA"],
    "enabled": false
  }
]

target = [{
    "name": "test1",
    "values": [{
        "value": "User Support",
        "selected": false
      },
      {
        "value": "Engineering",
        "selected": false
      },
      {
        "value": "Implementation",
        "selected": false
      }
    ],
    "enabled": false
  },
  {
    "name": "test2",
    "values": [{
        "value": "M",
        "selected": false
      },
      {
        "value": "F",
        "selected": false
      }
    ],
    "notEnabled": false
  },
  {
    "name": "test3",
    "values": [{
        "value": "CA",
        "selected": false
      },
      {
        "value": "EN",
        "selected": false
      }
    ],
    "enabled": false
  }
]

我想将这两个 JSON 字符串合并到目标中，结果应该如下所示:

target = [{
    "name": "test1",
    "values": [{
        "value": "User Support",
        "selected": true
      },
      {
        "value": "Engineering",
        "selected": false
      },
      {
        "value": "Implementation",
        "selected": false
      }
    ],
    "enabled": false
  },
  {
    "name": "test2",
    "values": [{
        "value": "M",
        "selected": true
      },
      {
        "value": "F",
        "selected": false
      }
    ],
    "enabled": true
  },
  {
    "name": "test3",
    "values": [{
        "value": "CA",
        "selected": true
      },
      {
        "value": "EN",
        "selected": false
      }
    ],
    "enabled": false
  }
]

因此，我要做的是在目标字符串中搜索名称为 test1、test2....，然后如果在源 JSON 字符串中找到该值，则将所选字段设置为 true。启用字段的情况也是如此。
我想到的第一件事是对每个循环使用嵌套并检查键。
在Javascript中还有其他更好的方法吗？
请注意，目标字符串中可能存在其他键，但除非它们存在于源字符串中，否则我们不会打扰它们。

如果你不介意lodash:

const _ = require('lodash');

const sourceJSON = '[{"name":"test1","values":["User Support"],"enabled":false},{"name":"test2","values":["M"],"enabled":true},{"name":"test3","values":["CA"],"enabled":false}]';
const targetJSON = '[{"name":"test1","values":[{"value":"User Support","selected":false}, {"value":"Engineering","selected":false},{"value":"Implementation","selected":false}],"enabled":false},{"name":"test2","values":[{"value":"M","selected":false},  {"value":"F","selected":false} ],"notEnabled":false},{ "name":"test3","values": [{"value":"CA","selected":false},{"value":"EN","selected":false}],"enabled":false}]';

const source = JSON.parse(sourceJSON);
const target = JSON.parse(targetJSON);

const sourceNormalized = source.map((obj) => (
  { ...obj, values: [{value: obj.values[0], selected: true}] }
));

const merged = _.defaultsDeep(sourceNormalized, target);
console.dir(merged, {depth: null});
// [ { name: 'test1',
//     values: [
//       { value: 'User Support', selected: true },
//       { value: 'Engineering', selected: false },
//       { value: 'Implementation', selected: false }
//     ],
//     enabled: false
//   },
//   { name: 'test2',
//     values: [ 
//       { value: 'M', selected: true }, 
//       { value: 'F', selected: false } 
//     ],
//     enabled: true,
//     notEnabled: false
//   },
//   { name: 'test3',
//     values: [
//       { value: 'CA', selected: true },
//       { value: 'EN', selected: false }
//     ],
//     enabled: false} ] 

result = JSON.stringify(merged);
