Javascript:读取关联数组的更好方法

Question

我有一个名为values的数组，其中包含对象

let values = [
{name: "firstname", value: "Mike"},

{name: "lastname", value: "Smith "},

{name: "emailaddress", value: "mike@test.com"},

{name: "role", value: "123"}]


// Then I have code like this, which works

let editUser = {
    "firstnameofperson": values[0].value,
    "lastnameofperson": values[1].value,
    "emailaddress": values[2].value,
    "roleofperson": values[3].value,
}

console.log(editUser);

有没有更好的方法来做到这一点，而不是指定数组值[x]索引等。

顺便说一句，我正在使用 ES6

执行此操作的一种方法可能是:

(注意:“emailaddressofperson”，而不是“emailaddress”，但这是一个连贯性问题，您应该根据此答案更改属性名称 - 甚至删除“ofperson”后缀)

let arr = [
    { name: "firstname"    , value: "Mike"          }
  , { name: "lastname"     , value: "Smith "        }
  , { name: "emailaddress" , value: "mike@test.com" }
  , { name: "role"         , value: "123"           }
]
  
let editUser = {};

arr.forEach( x => editUser[x.name+'ofperson'] = x.value )

console.log(editUser);

.as-console-wrapper { max-height: 100% !important; top: 0; }
