最近從實際業務抽象出了一些功能和數據結構，開始思考什么結構才算是好的數據結構？效率，可復用性，易懂？

一、案例

1、方便取值

{"data": {"park": [{"id": 12,"name": "aaa"},{"id": 3,"name": "bbb"}],"video": [{"id": 124,"name": "aaa","url": ""},{"id": 34,"name": "bbb","url": ""}]} }

2、可讀性

{"data": [{"type": "park","subData": [{"id": 12,"name": "aaa"},{"id": 3,"name": "bbb"}]},{"type": "video","subData": [{"id": 124,"name": "aaa","url": ""},{"id": 34,"name": "bbb","url": ""}]}] }

3、通用

{"data": [{"type": "park","id": 12,"name": "aaa"},{"type": "park","id": 3,"name": "bbb"},{"type": "video","id": 124,"name": "aaa","url": ""},{"type": "video","id": 34,"name": "bbb","url": ""}] }

二、數據格式轉換

針對上述3種格式，編寫相互轉換的函數，請移步。
