作为对亚当·博杜赫的回答的补充，这个问题考虑到了性质的差异

const differenceOfKeys = (...objects) =>
  _.difference(...objects.map(obj => Object.keys(obj)));
const differenceObj = (a, b) => 
  _.reduce(a, (result, value, key) => (
    _.isEqual(value, b[key]) ? result : [...result, key]
  ), differenceOfKeys(b, a));

此解决方案返回一个具有修改过的属性的对象。

_.reduce(a, (r, v, k) => { return _.merge(r, _.isEqual(v, b[k]) ? {} : { [k]: v }); }, {});

一个简单而优雅的解决方案是使用_。isEqual，它执行深度比较:

Var a = {}; Var b = {}; A.prop1 = 2; A.prop2 = {prop3: 2}; B.prop1 = 2; B.prop2 = {prop3: 3}; console.log(_。isEqual (a, b));//如果不同则返回false < script src = " https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.min.js " > < /脚本>

然而，这个解决方案并没有显示哪个属性是不同的。

深度比较使用模板的(嵌套)属性进行检查

function objetcsDeepEqualByTemplate(objectA, objectB, comparisonTemplate) {
  if (!objectA || !objectB) return false

  let areDifferent = false
  Object.keys(comparisonTemplate).some((key) => {
    if (typeof comparisonTemplate[key] === 'object') {
      areDifferent = !objetcsDeepEqualByTemplate(objectA[key], objectB[key], comparisonTemplate[key])
      return areDifferent
    } else if (comparisonTemplate[key] === true) {
      areDifferent = objectA[key] !== objectB[key]
      return areDifferent
    } else {
      return false
    }
  })

  return !areDifferent
}

const objA = { 
  a: 1,
  b: {
    a: 21,
    b: 22,
  },
  c: 3,
}

const objB = { 
  a: 1,
  b: {
    a: 21,
    b: 25,
  },
  c: true,
}

// template tells which props to compare
const comparisonTemplateA = {
  a: true,
  b: {
    a: true
  }
}
objetcsDeepEqualByTemplate(objA, objB, comparisonTemplateA)
// returns true

const comparisonTemplateB = {
  a: true,
  c: true
}
// returns false
objetcsDeepEqualByTemplate(objA, objB, comparisonTemplateB)

这将在控制台中工作。如果需要，可以添加数组支持

这是我对这个问题的解决办法

const _ = require('lodash');

var objects = [{ 'x': 1, 'y': 2, 'z':3, a:{b:1, c:2, d:{n:0}}, p:[1, 2, 3]  }, { 'x': 2, 'y': 1, z:3, a:{b:2, c:2,d:{n:1}}, p:[1,3], m:3  }];

const diffFn=(a,b, path='')=>_.reduce(a, function(result, value, key) {

    if(_.isObjectLike(value)){
      if(_.isEqual(value, b[key])){
        return result;
      }else{

return result.concat(diffFn(value, b[key], path?(`${path}.${key}`):key))
      }
    }else{
return _.isEqual(value, b[key]) ?
        result : result.concat(path?(`${path}.${key}`):key);
    }
    
}, []);

const diffKeys1=diffFn(objects[0], objects[1])
const diffKeys2=diffFn(objects[1], objects[0])
const diffKeys=_.union(diffKeys1, diffKeys2)
const res={};

_.forEach(diffKeys, (key)=>_.assign(res, {[key]:{ old: _.get(objects[0], key), new:_.get(objects[1], key)} }))

res
/*
Returns
{
  x: { old: 1, new: 2 },
  y: { old: 2, new: 1 },
  'a.b': { old: 1, new: 2 },
  'a.d.n': { old: 0, new: 1 },
  'p.1': { old: 2, new: 3 },
  'p.2': { old: 3, new: undefined },
  m: { old: undefined, new: 3 }
}
*/

这是一个简单的带有Lodash深度差异检查器的Typescript，它将生成一个新对象，只包含旧对象和新对象之间的差异。

例如，如果我们有:

const oldData = {a: 1, b: 2};
const newData = {a: 1, b: 3};

结果对象将是:

const result: {b: 3};

它还兼容多层深层对象，对于数组，它可能需要一些调整。

import * as _ from "lodash";

export const objectDeepDiff = (data: object | any, oldData: object | any) => {
  const record: any = {};
  Object.keys(data).forEach((key: string) => {
    // Checks that isn't an object and isn't equal
    if (!(typeof data[key] === "object" && _.isEqual(data[key], oldData[key]))) {
      record[key] = data[key];
    }
    // If is an object, and the object isn't equal
    if ((typeof data[key] === "object" && !_.isEqual(data[key], oldData[key]))) {
      record[key] = objectDeepDiff(data[key], oldData[key]);
    }
  });
  return record;
};
