javascript:通过链接两个数组创建一个 JSON 对象数组

Question

假设我有两个数组:

  var  meals: ["breakfast", "lunch", "dinner"];
  var ingredients: [["eggs", "yogurt", "toast"],["falafel", "mushrooms", "fries"], ["pasta", "cheese"];

是否有一个优雅的解决方案来创建一个具有以下特征的 JavaScript 对象数组:

var dailySchedule = {"breakfast" : ["eggs", "yogurt", "toast"],
                      "lunch": ["falafel", "mushrooms", "fries"],
                      "dinner": ["pasta", "cheese"]
}

我知道它应该是 .reduce 的东西，但我一直在摸索如何去做......

Answer 1

当然，你可以减少它

var meals = ["breakfast", "lunch", "dinner"];
var ingredients = [
  ["eggs", "yogurt", "toast"],
  ["falafel", "mushrooms", "fries"],
  ["pasta", "cheese"]
];

var dailySchedule = meals.reduce( (a,b, i) => {
	return a[b] = ingredients[i], a;
},{});

console.log(dailySchedule)

.as-console-wrapper {top : 0}
