我有一個(gè)函數(shù)可以減少屬性數(shù)組并構(gòu)建一個(gè)對象：type FieldProps = {  name: string;  value: string;  required: boolean;  styles?: object;  className?: string}const fields: FieldProps[] = [  {    name: "firstName",    value: "Bob",    required: true,    styles: { width: "100%"}  },  {    name: "lastName",    value: "Smith",    required: true,    className: "example"  },  {    name: "city",    value: "Tulsa",    required: true,  },  {    name: "state",    value: "OK",    required: true,  },]const parseFields = <T extends any[], K extends object = {}>(fields: T): K => {  try {    if (!fields || (fields && fields.length < 0)) throw new Error("You must supply an array of fields!");    const parsedFields = fields.reduce((acc, { name, value }: { name: string, value: string}) => {      switch (name) {        case "city":        case "street":        case "state":        case "suite":        case "zipCode": {          acc["address"] = acc["address"] || {};          if (value) acc.address[name] = value;          break;        }        default: {          acc[name] = value;          break;        }      }      return acc;    }, {} as K);    return parsedFields;  } catch (err) {    throw String(err);  }};const userDetails = parseFields(fields);截至目前，懸停在上方userDetails會顯示一個(gè)空對象類型( {})，理想情況下應(yīng)該是：{  "firstName": string,  "lastName": string,  "address": {    "city": string,    "state": string  }}我如何重構(gòu)函數(shù)以獲取類型FieldProps[]并讓它返回動態(tài)類型的對象？
