如何使用 UnderscoreJS、Omit 和少数条件组合所有内容？

Question

const objA = {
    name: 'jack',
    age: '24',
    address : '#210-1101',
    zip : '10114',
    Zip1 : '22222',
    accountNo : '12345667890',
    bankName : 'KB',
    amount : '1000',
    currency : 'USD',
    country : 'USA'
  };
  
  const objB = {
    name: 'eddie',
    lastName : 'bauer',
    addressDetail : '',
    address: '#210-1101',
    zip: '10114',
    currency : 'EUR',
    country : 'FRA'
  };
  
  const isSame = (v,k) => objA[k] === v;

  const tmpRet =  _(objB).omit(isSame);

  const isName = (tmpRet, k) =>  k === 'name' ? Object.assign(tmpRet, {date: '19780708'}, {}) : '';

  const isCurrency = (tmpRet, k) => k === 'currency' ? Object.assign(tmpRet, {currency2: 'USD'}, {}) : '';

  const checkCondition = (tmpRet, k) => { isName(tmpRet, k); isCurrency(tmpRet, k); };

  const goFunc = () => _(tmpRet).each( (v,k) => checkCondition(tmpRet, k));

  goFunc();
  console.log(tmpRet );

我有一个类似于上面的代码，但我无法将它们全部放在一起。

我想让它更实用，更单行。

有什么建议吗？？

谢谢

您可能正在寻找这样的东西：

import _ from "underscore";

const objA = {
  name: "jack",
  age: "24",
  address: "#210-1101",
  zip: "10114",
  Zip1: "22222",
  accountNo: "12345667890",
  bankName: "KB",
  amount: "1000",
  currency: "USD",
  country: "USA"
};

const objB = {
  name: "eddie",
  lastName: "bauer",
  addressDetail: "",
  address: "#210-1101",
  zip: "10114",
  currency: "EUR",
  country: "FRA"
};

const compose = (...fns) => (tmp, k) =>
  fns.reduceRight((acc, fn) => fn(acc, k), tmp);

const isSame = (v, k) => objA[k] === v;

const omit = (obj) => _(obj).omit(isSame);

const hasProperty = (obj, prop) =>
  Object.prototype.hasOwnProperty.call(obj, prop);

const isName = (tmp) =>
  hasProperty(tmp, "name")
    ? {
        ...tmp,
        date: "19780708"
      }
    : tmp;

const isCurrency = (tmp, k) =>
  hasProperty(tmp, "currency")
    ? {
        ...tmp,
        currency2: "USD"
      }
    : tmp;

const goFunc = () => compose(isName, isCurrency, omit)(objB);

const result = goFunc();

我相信你可以跳过每个键的迭代
