Posted 2020-12-03 江山一族

let arr = [{
"code": "badge",
"priceList": [{
"amount": 3000
}]
},

{
"code": "DigitalPhoto",
"priceList": [{
"amount": 1990
}]
}
]

let arr2 = arr.reduce((pre,cur)=>{
pre[cur.code] = cur.priceList
return pre
},{})
console.log(arr2)

打印结果：

{ badge: [ { amount: 3000 } ],
DigitalPhoto: [ { amount: 1990 } ] }
