對象的映射函數（而不是數組） - map function for objects (instead of arrays)

問題：

I have an object:我有一個對象：

myObject = { 'a': 1, 'b': 2, 'c': 3 }

I am looking for a native method, similar to Array.prototype.map that would be used as follows:我正在尋找一種類似於Array.prototype.map的本機方法，其用途如下：

newObject = myObject.map(function (value, label) {
    return value * value;
});

// newObject is now { 'a': 1, 'b': 4, 'c': 9 }

Does JavaScript have such a map function for objects? JavaScript 有這樣的對象map函數嗎？ (I want this for Node.JS, so I don't care about cross-browser issues.) （我想要這個用於 Node.JS，所以我不關心跨瀏覽器的問題。）
