javascript - 如何将一组对象拆分为多个普通数组，其中每个数组由一个属性的值填充？

Question

我有一个对象数组如下:

var GOM = [{name:"Kuroko",ability:"misdirection"},
           {name:"Kise",ability:"perfect copy"},
           {name: "Akashi", ability: "emperor's eye"}];

是否可以使用 lodash 或 native javascript(不是 forEach)中的一些预定义函数将其拆分为 2 个数组。

["Kuroko","Kise","Akashi"] and ["misdirection","perfect copy","emperor's eye"]

我知道我可以做到这一点:

var names = [];
var abilities = [];
GOM.forEach(function(member){
  names.push(member.name);
  abilities.push(member.ability);
});

但我正在寻找另一种方式。

Answer 1

合并 map() , values() , 和 unzip()放入包装器中:

var wrapper = _(GOM).map(_.values).unzip();

然后很容易抓取名字:

wrapper.first()
// → [ "Kuroko", "Kise", "Akashi" ]

能力:

wrapper.last()
// → [ "misdirection", "perfect copy", "emperor's eye" ]
