平时工作中，时常要打印一些对象到控制台，但平常的console.log只能看到最外的一层，里边的都会以[Object]隐藏掉 如：
[ { id: ‘300760‘, data: [ [Object], [Object] ] },
{ id: ‘300529‘,
data:
[ [Object],
[Object],
[Object],
[Object],
[Object],
[Object],
[Object],
[Object],
[Object] ] },
]
可以用console.dir(object, {depth:null}} 来显示全部
[ { id: ‘300760‘,
data:
[ { code: ‘300760‘, season: ‘2018-12-31‘, profit: 369067 },
{ code: ‘300760‘, season: ‘2019-12-31‘, profit: 461498 } ] },
{ id: ‘300529‘,
data:
[ { code: ‘300529‘, season: ‘2011-12-31‘, profit: 7100 },
{ code: ‘300529‘, season: ‘2012-12-31‘, profit: 9361 },
{ code: ‘300529‘, season: ‘2013-12-31‘, profit: 12099 },
{ code: ‘300529‘, season: ‘2014-12-31‘, profit: 14566 },
{ code: ‘300529‘, season: ‘2015-12-31‘, profit: 19390 },
{ code: ‘300529‘, season: ‘2016-12-31‘, profit: 19413 },
{ code: ‘300529‘, season: ‘2017-12-31‘, profit: 24517 },
{ code: ‘300529‘, season: ‘2018-12-31‘, profit: 35224 },
{ code: ‘300529‘, season: ‘2019-12-31‘, profit: 52199 } ] },
]
可以看到相当pretty了
