如何使用 typescript 展平 json 阵列并将其转换为 object

Question

I am trying to convert a json array as a flat json using typescript. I have a json as below:

"Fields" : [
    {
    "FieldName" : "xyz";
    "FieldValue" : {
     "Contents": {
      " Company": "ABC"
    }
    }
    }
    ]

I have to convert as below:

"xyz" :  {
      "Contents": {
      " Company": "ABC"
     }
    }
Here Fields should be replaced with "xyz", FieldName and FieldValue should need to be removed. 

Help me to achieve this using typescript.

If you really only want to work with that first item in your array just rearrange the data with something the following.

 const json = JSON.stringify({ Fields: [ { FieldName: "xyz", FieldValue: { Contents: { " Company": "ABC" } } } ] }); const parsedJson = JSON.parse(json); const expectedOutput = { [parsedJson.Fields[0].FieldName]: parsedJson.Fields[0].FieldValue }; console.log(expectedOutput);
