javascript function 获取对象列表并在新数组中返回具有新值的新键

Question

为了隐私，我解释了一个简单的例子。 function 获取个人列表并返回具有新值的新密钥，如下所示：

personalList = [{
        firstName: "elena",
        lastName: "zakharova"
    },
    {
        firstName: "alex",
        lastName: "farmanda"
    },
    {
        firstName: "mike",
        lastName: "kenan"
    }]

output应该是这样的：

desiredList =[{fullname :'elena zakhrova'},{fullname :'alex farmanda'}, fullname : 'mike kenan']

尝试了一些方法但不幸的是没有得到答案

任何解决方案将不胜感激。

Answer 1

您可以使用 map

 const personalList = [{ firstName: "elena", lastName: "zakharova" }, { firstName: "alex", lastName: "farmanda" }, { firstName: "mike", lastName: "kenan" }] console.log(personalList.map(({firstName,lastName}) => ({fullName: `${firstName} ${lastName}`})))

Answer 2

下面是我如何使用 For 循环解决这个问题。 您也可以像@R4ncid 解释的那样使用地图

 var desiredlist = [] var personalList = [{ firstName: "elena", lastName: "zakharova" }, { firstName: "alex", lastName: "farmanda" }, { firstName: "mike", lastName: "kenan" }] for (i=0;i<personalList.length;i++){ desiredlist.push({"fullname":personalList[i].firstName + " " + personalList[i].lastName})} console.log(desiredlist)
