javascript - 使用javascript从数组创建一个对象

Question

我有两个按顺序包含国家代码和货币的数组列表，但我需要知道如何组合并形成以下格式的对象。

var cn =["AL","DZ","AS","AD","AO","AI","AG","AR","AM","AW","AU"];
var ccy = ["ALL","DZD","USD","EUR","AOA","XCD","XCD","ARS","AMD","AWG","AUD"];

预期输出:

country:[
{
  "code": "AL",
  "currency": ["ALL"]
},
{
  "code": "DZ",
  "currency": ["DZD"]
}...
...
{
  "code": "AU",
  "currency": ["AUD"]
}
]

Answer 1

您可以使用 map 并使用 index 从第二个数组访问相应的值

var cn =["AL","DZ","AS","AD","AO","AI","AG","AR","AM","AW","AU"];
var ccy = ["ALL","DZD","USD","EUR","AOA","XCD","XCD","ARS","AMD","AWG","AUD"];

let final = cn.map((code,index)=>{
  let currency = ccy[index]
  return {code, currency: [currency]}
})

console.log(final)
