javascript - 使用 underscore.js 将多个数组组合为对象集合

Question

我有一些通过数组收集的信息，例如:

var names = ["Jack", "Marry", "Bob"]
var cars = ["Audi", "BMW", "Volvo"]

我希望这些信息组合成像集合一样的对象，例如:

[{name:"Jack", car: "Audi"}, {name: "Marry", car:"BMW"}, {name:"Bob", car:"Volvo"}]

我可以通过一些步骤来做到这一点:

var combine = _.zip(names, cars)
var collection= _.map(combine, function(info){
                      return _.object(["name", "car"], info);
                     });

还有其他方法可以让代码看起来更好吗？ 谢谢

Answer 1

es5怎么样array.map() ？

var names = ["Jack", "Marry", "Bob"]
var cars = ["Audi", "BMW", "Volvo"]

var result = names.map(function(val, key){
 return {name: val, car: cars[key]}
})

console.log(result); //[{car: "Audi", name: "Jack"}, {car: "BMW", name: "Marry"}, {car: "Volvo", name: "Bob"}]

附注如果数组有不同的长度，请添加一个条件
