通过等同于对象数组并将其替换为来自同一对象数组集合的新值来查找对象中的值

Question

我有一个对象数组和一个对象对象：

let newSet = [{
    "newName": "New One",
    "oldName": "old one"
  },
  {
    "newName": "New two",
    "oldName": "old two"
  },
  {
    "newName": "New Three",
    "oldName": "old three"
  }
];

let property = {
  companies: [{
    products: [{
        lob: {
          description: "old two"
        }
      },
      {
        lob: {
          description: "old three"
        }
      }
    ]
  }]
};

现在我在这里尝试检查 property 对象是否具有来自 newSet 数组的 oldName 的 lob's description 值，然后它应该被替换为来自 @ 的相同对象的 newName 987654327@数组

预期输出：

let property = {
  companies: [{
    products: [{
        lob: {
          description: "New two"
        }
      },
      {
        lob: {
          description: "New Three"
        }
      }
    ]
  }]
};

注意：其中可能有多家公司及其多种产品

Answer 1

从 newSet 创建对象映射 {[oldName]: newName}。
遍历所有公司和每个公司的产品，在对象映射中找到描述，如果存在则替换为 newName 值。

const map = Object.fromEntries(newSet.map(({oldName,newName})=>[oldName,newName]))
for(const {products} of property.companies)
  for(const {lob} of products)
    if(map[lob.description])
      lob.description = map[lob.description]

console.log(property)

<script>
  let newSet = [{
      "newName": "New One",
      "oldName": "old one"
    },
    {
      "newName": "New two",
      "oldName": "old two"
    },
    {
      "newName": "New Three",
      "oldName": "old three"
    }
  ];

  let property = {
    companies: [{
      products: [{
          lob: {
            description: "old two"
          }
        },
        {
          lob: {
            description: "old three"
          }
        }
      ]
    }]
  };
</script>
