以Sridhar Gudimela的回答为基础，下面以一种使用TypeScript的方式进行了更新:

///  U T I L S

interface LooseObjectInterface {
  [key: string]: any;
};

type inputOptions = LooseObjectInterface | any[];



///  E X P O R T

export const objectCompare = (objectA: inputOptions, objectB: inputOptions): LooseObjectInterface => {
  let diffObj: LooseObjectInterface = {};

  switch(true) {
    case (Array.isArray(objectA)):
      objectA.forEach((elem: any, index: number) => {
        if (!Array.isArray(diffObj))
          diffObj = [];

        diffObj[index] = objectCompare(elem, (objectB || [])[index]);
      });

      break;

    case (objectA !== null && typeof objectA === "object"):
      Object.keys(objectA).forEach((key: any) => {
        if (Array.isArray(objectA[key])) {
          let arr = objectCompare(objectA[key], objectB[key]);

          if (!Array.isArray(arr))
            arr = [];

          arr.forEach((elem: any, index: number) => {
            if (!Array.isArray(diffObj[key]))
              diffObj[key] = [];

            diffObj[key][index] = elem;
          });
        } else if (typeof objectA[key] === "object")
          diffObj[key] = objectCompare(objectA[key], objectB[key]);
        else if (objectA[key] !== (objectB || {})[key])
          diffObj[key] = objectA[key];
        else if (objectA[key] === (objectB || {})[key])
          delete objectA[key];
      });

      break;

    default:
      break;
  }

  Object.keys(diffObj).forEach((key: any) => {
    if (typeof diffObj[key] === "object" && JSON.stringify(diffObj[key]) === "{}")
      delete diffObj[key];
  });

  return diffObj;
};

编辑:我最初的回答使用了Flow，因此被否决了(我猜，或者可能是因为我的回答没有使用Lodash……)然而，有一个类似问题的答案也无妨)。

要递归地显示一个对象与其他对象的不同之处，可以使用_。Reduce与_结合。isEqual和_.isPlainObject。在这种情况下，你可以比较a与b的不同，或者b与a的不同:

const objectA = { a: { 1: "SAME WILL BE MISSING IN RESULT", 2: "BBB", 3: [1, 2, 3] }, b: "not", c: "foo bar" }; const objectB = { a: { 1: "SAME WILL BE MISSING IN RESULT", 2: [1, 2] }, b: "foo", c: "bar" }; const diff = function(obj1, obj2) { return _.reduce(obj1, function(result, value, key) { if (_.isPlainObject(value)) { result[key] = diff(value, obj2[key]); } else if (!_.isEqual(value, obj2[key])) { result[key] = value; } return result; }, {}); }; const diffAOverB = diff(objectA, objectB); const diffBOverA = diff(objectA, objectB); console.log(diffAOverB); console.log(diffBOverA); <script src="https://cdn.jsdelivr.net/npm/lodash@4.17.4/lodash.min.js"></script>

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 }
}
*/

这是基于@JLavoie，使用lodash

let differences = function (newObj, oldObj) {
      return _.reduce(newObj, function (result, value, key) {
        if (!_.isEqual(value, oldObj[key])) {
          if (_.isArray(value)) {
            result[key] = []
            _.forEach(value, function (innerObjFrom1, index) {
              if (_.isNil(oldObj[key][index])) {
                result[key].push(innerObjFrom1)
              } else {
                let changes = differences(innerObjFrom1, oldObj[key][index])
                if (!_.isEmpty(changes)) {
                  result[key].push(changes)
                }
              }
            })
          } else if (_.isObject(value)) {
            result[key] = differences(value, oldObj[key])
          } else {
            result[key] = value
          }
        }
        return result
      }, {})
    }

在没有使用lodash/下划线的情况下，我已经编写了这段代码，并且可以很好地对object1和object2进行深入比较

function getObjectDiff(a, b) {
    var diffObj = {};
    if (Array.isArray(a)) {
        a.forEach(function(elem, index) {
            if (!Array.isArray(diffObj)) {
                diffObj = [];
            }
            diffObj[index] = getObjectDiff(elem, (b || [])[index]);
        });
    } else if (a != null && typeof a == 'object') {
        Object.keys(a).forEach(function(key) {
            if (Array.isArray(a[key])) {
                var arr = getObjectDiff(a[key], b[key]);
                if (!Array.isArray(arr)) {
                    arr = [];
                }
                arr.forEach(function(elem, index) {
                    if (!Array.isArray(diffObj[key])) {
                        diffObj[key] = [];
                    }
                    diffObj[key][index] = elem;
                });
            } else if (typeof a[key] == 'object') {
                diffObj[key] = getObjectDiff(a[key], b[key]);
            } else if (a[key] != (b || {})[key]) {
                diffObj[key] = a[key];
            } else if (a[key] == (b || {})[key]) {
                delete a[key];
            }
        });
    }
    Object.keys(diffObj).forEach(function(key) {
        if (typeof diffObj[key] == 'object' && JSON.stringify(diffObj[key]) == '{}') {
            delete diffObj[key];
        }
    });
    return diffObj;
}

我需要知道它们的某个嵌套属性是否不同

其他答案为这个问题提供了可能令人满意的解决方案，但它非常困难和常见，似乎有一个非常受欢迎的包来帮助解决这个问题。

要使用这个包，你需要npm i deep-object-diff，然后:

const { diff } = require('deep-object-diff');
var a = {};
var b = {};

a.prop1 = 2;
a.prop2 = { prop3: 2 };

b.prop1 = 2;
b.prop2 = { prop3: 3 };

if (!_.isEqual(a, b)) {
  const abDiff = diff(a, b);
  console.log(abDiff);
  /*
  {
    prop2: {
      prop3: 3
    }
  }
  */
}

// or alternatively
const abDiff = diff(a, b);
if(!_.isEmpty(abDiff)) {
  // if a diff exists then they aren't deeply equal
  // perform needed actions with diff...
}

下面是一个更详细的案例，直接从他们的文档中删除属性:

const lhs = {
  foo: {
    bar: {
      a: ['a', 'b'],
      b: 2,
      c: ['x', 'y'],
      e: 100 // deleted
    }
  },
  buzz: 'world'
};

const rhs = {
  foo: {
    bar: {
      a: ['a'], // index 1 ('b')  deleted
      b: 2, // unchanged
      c: ['x', 'y', 'z'], // 'z' added
      d: 'Hello, world!' // added
    }
  },
  buzz: 'fizz' // updated
};

console.log(diff(lhs, rhs)); // =>
/*
{
  foo: {
    bar: {
      a: {
        '1': undefined
      },
      c: {
        '2': 'z'
      },
      d: 'Hello, world!',
      e: undefined
    }
  },
  buzz: 'fizz'
}
*/
