ES6:我能做到的最小代码是这样的。它通过对代表对象的所有键值数组进行字符串化来进行递归的深度比较，唯一的限制是没有方法或符号进行比较。

const compareObjects = (a, b) => { let s = (o) => Object.entries(o).sort()。映射(i => { if(i[1]实例对象)i[1] = s(i[1]); 返回我 }) 返回JSON.stringify(s(a)) === JSON.stringify(s(b)) ｝ console.log (compareObjects ({b: 4,答:{b: 1}}, {} {b: 1, b: 4}));

重要提示:这个函数正在执行JSON。stringfy在数组中，并将键排序，而不是在对象本身中:

["a" ["b"， 1]] [" b ", 4]

如果你的问题是检查两个对象是否相等，那么这个函数可能会有用

function equals(a, b) {
const aKeys = Object.keys(a)
const bKeys = Object.keys(b)
if(aKeys.length != bKeys.length) {
    return false
}
for(let i = 0;i < aKeys.length;i++) {
    if(aKeys[i] != bKeys[i]) {
        return false
    } 
}
for(let i = 0;i < aKeys.length;i++) {
    if(a[aKeys[i]] != b[bKeys[i]]) {
        return false
    }
}
return true
}

first we check if the length of the list of keys of these objects is the same, if not we return false to check if two objects are equal they must have the same keys(=names) and the same values of the keys, so we get all the keys of objA, and objB and then we check if they are equal once we find that tow keys are not equal then we return false and then when all the keys are equal then we loop through one of the keys of one of the objects and then we check if they are equal once they are not we return false and after the two loops finished this means they are equal and we return true NOTE: this function works with only objects with no functions

let user1 = { name: "John", address: { line1: "55 Green Park Road", line2: { a:[1,2,3] } }, email:null } let user2 = { name: "John", address: { line1: "55 Green Park Road", line2: { a:[1,2,3] } }, email:null } // Method 1 function isEqual(a, b) { return JSON.stringify(a) === JSON.stringify(b); } // Method 2 function isEqual(a, b) { // checking type of a And b if(typeof a !== 'object' || typeof b !== 'object') { return false; } // Both are NULL if(!a && !b ) { return true; } else if(!a || !b) { return false; } let keysA = Object.keys(a); let keysB = Object.keys(b); if(keysA.length !== keysB.length) { return false; } for(let key in a) { if(!(key in b)) { return false; } if(typeof a[key] === 'object') { if(!isEqual(a[key], b[key])) { return false; } } else { if(a[key] !== b[key]) { return false; } } } return true; } console.log(isEqual(user1,user2));

我看到了意大利式的代码答案。 不使用任何第三方的lib，这是非常容易的。

首先，按键对两个对象进行排序。

let objectOne = { hey, you }
let objectTwo = { you, hey }

// If you really wanted you could make this recursive for deep sort.
const sortObjectByKeyname = (objectToSort) => {
    return Object.keys(objectToSort).sort().reduce((r, k) => (r[k] = objectToSort[k], r), {});
}

let objectOne = sortObjectByKeyname(objectOne)
let objectTwo = sortObjectByKeyname(objectTwo)

然后简单地使用字符串来比较它们。

JSON.stringify(objectOne) === JSON.stringify(objectTwo)

排序对象(字典) 比较JSON字符串 函数areTwoDictsEqual(dictA, dictB) { 函数sortDict(dict) { var keys = Object.keys(dict); keys.sort (); var newDict = {}; For (var i=0;我< keys.length;我+ +){ Var key = keys[i]; Var值= dict[key]; newDict[key] = value; ｝ 返回newDict; ｝ 返回JSON.stringify(sortDict(dictA)) == JSON.stringify(sortDict(dictB)); ｝

const one={name:'mohit' , age:30};
//const two ={name:'mohit',age:30};
const two ={age:30,name:'mohit'};

function isEquivalent(a, b) {
// Create arrays of property names
var aProps = Object.getOwnPropertyNames(a);
var bProps = Object.getOwnPropertyNames(b);



// If number of properties is different,
// objects are not equivalent
if (aProps.length != bProps.length) {
    return false;
}

for (var i = 0; i < aProps.length; i++) {
    var propName = aProps[i];

    // If values of same property are not equal,
    // objects are not equivalent
    if (a[propName] !== b[propName]) {
        return false;
    }
}

// If we made it this far, objects
// are considered equivalent
return true;
}

console.log(isEquivalent(one,two))
