最近從實(shí)際業(yè)務(wù)抽象出了一些功能和數(shù)據(jù)結(jié)構(gòu)，開(kāi)始思考什么結(jié)構(gòu)才算是好的數(shù)據(jù)結(jié)構(gòu)？效率，可復(fù)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(shù)據(jù)格式轉(zhuǎn)換

針對(duì)上述3種格式，編寫(xiě)相互轉(zhuǎn)換的函數(shù)，請(qǐng)移步。
