对比两个对象是否相等

[nunnly]

深入对比两个对象（key相同）value是否相等，如果相等返回true，如果不等，返回不相等的字段的key用.分隔，

function compareObject(obj1, obj2) {

}
const a = {a:1, b: 2, c:{d:1}}
const b = {a: 1, b: 2, c:{d:2}}
compareObject(a, b);
// => ['c.d']

const c = {a:1, b: 2, c:{d:1, f: 2}};
const d = {a:1, b: 3, c:{d:5, f: 1}};
compareObject(c, d);
// => ['b', 'c.d', 'c.f']

 newlist = newlist.map(function (value) {

 list = list.concat(newlist)

不知道是以 obj1 的 key 为基准还是所有 key

function merge(keys1, keys2){
 var keys = [].concat(keys1);
 keys2.forEach(function (i){
 if (keys.indexOf(i) === -1){
 keys.push(i);
 }
 });
 return keys;
}

function compareObject(obj1, obj2){
 var keys1 = Object.keys(obj1);
 var keys2 = Object.keys(obj2);
 var keys = merge(keys1, keys2);
 var result = [];
 keys.forEach(function (key){
 if (typeof obj1[key] === 'object' && typeof obj2[key] === 'object'){
 var children = compareObject(obj1[key], obj2[key]);
 if (children !== true) {
 children = children.map(function (i){
 return key + '.' + i;
 });
 result = result.concat(children);
 }
 }else if (obj1[key] !== obj2[key]) {
 result.push(key);
 }
 });
 return !result.length ? true : result;
}

JSON.stringify 有键值顺序风险并忽略一些值。

这个代码放在浏览器里面运行报错,代码如下:
`var bbbb = {a:1, b: 2, c:{d:1}}
var cccc = {a: 1, b: 2, c:{d:2}}
compareObject(bbbb,cccc);
function compareObject(obj1, obj2) {
var list = []
for(var key in obj1) {
if(typeof obj1[key] === 'object') {
var newlist = compareObject(obj1[key], obj2[key])
if(Object.prototype.toString.call(newlist) === "[object Array]") {
//把遍历对象里得到的不同的值放到数组里面去.
newlist = newlist.map(function (value) {
return key + '.' +value
})
list = list.concat(newlist)
}

 } else if(obj1[key] != obj2[key]) {
 list.push(key)
 }
 return list.length == 0? true: list

}
}`
报错信息:

找不到什么原因,求指导.
