如下：{1:222, 2:123, 5:888}，请把数据处理为如下结构：[222, 123, null, null, 888, null, null, null, null, null, null, null]。

function mapData(obj) {
	let month = new Array(12).fill(null);
	const monthKeys = Object.keys(obj);
	monthKeys.map((key) => {
		month[key-1] = obj[key]
	});
	return month;
}
mapData({1:222, 2:123, 5:888});
