下面的一些解决方案在性能、功能和风格方面存在问题……它们没有经过充分的考虑，其中一些在不同的情况下失败了。我试图在自己的解决方案中解决这个问题，我非常感谢您的反馈:

它会尽可能快地返回false，但当然，对于一个差异嵌套很深的大对象，它可能不那么有效。在我自己的场景中，良好地处理嵌套数组非常重要。

希望它能帮助需要这种“轮子”的人。

const isEqual = function (var1, var2) {
    if (typeof var1 === 'object' && typeof var2 === 'object') {
        // Checking equality for each of the inner values of the objects
        const keys = [...new Set([...Object.keys(var1),...Object.keys(var2)])];
        return keys.every(key => isEqual(var1[key], var2[key]) && isEqual(var2[key], var1[key]));
    } else { // Primitive types (number, boolean etc..)
        return var1 === var2; // Normal equality
    }
}

我在这里看到了很多很好的答案，但我找不到一个简短的函数，所以我创建了一个。 这将检查两个变量是否相等，无论其类型如何。 希望你看得合适。

如果你真的想比较并返回两个对象的差值。 您可以使用这个包:https://www.npmjs.com/package/deep-diff

或者只使用这个包使用的代码

https://github.com/flitbit/diff/blob/master/index.js

只是不要把它转换成字符串进行比较。
