javascript - 多个键名，相同的对值

Question

我正在尝试在 JavaScript 脚本中设置一个对象文字，该脚本具有具有多个名称的键。引用相同的对象值，即我已经尝试过的类似内容:

var holidays: {
    "thanksgiving day", "thanksgiving", "t-day": {
        someValue : "foo"
    }
}

var holidays: {
    ["thanksgiving day", "thanksgiving", "t-day"]: {
        someValue : "foo"
    }
}

有什么办法可以实现这个目标吗？

另一种方法是进行一些后处理

function expand(obj) {
    var keys = Object.keys(obj);
    for (var i = 0; i < keys.length; ++i) {
        var key = keys[i],
            subkeys = key.split(/,\s?/),
            target = obj[key];
        delete obj[key];
        subkeys.forEach(function(key) { obj[key] = target; })
    }
    return obj;
}

var holidays = expand({
    "thanksgiving day, thanksgiving, t-day": {
        someValue : "foo"
    } 
});
