javascript - 将三个数组转换为嵌套对象

Question

我想创建一个嵌套对象，如下所示

var obj; 
obj = [
    {
        "a": {
            "A" : "aA",
            "B" : "aB",
            "C" : "aC"
        }

    },
    {
        "b": {
            "A" : "bA",
            "B" : "bB",
            "C" : "bC"
        }

    },
    {
        "c": {
            "A" : "cA",
            "B" : "cB",
            "C" : "cC"
        }

    },      
]

来自这样的三个数组

var arr1 = ["a","b","c"]
var arr2 = ["A","B","C"]
var arr3 = [["aA","aB","aC"],["bA","bB","bC"], ["cA","cB","cC"]]

使用 lodash 或 es6 有简单的方法吗？我本质上是使用另一个函数从 arr1 和 arr2 生成 arr3 。但这在这里没有多大意义，但是如果我要创建这样的多个数据数组，并且我想通过组合数组来生成类似 JSON 的对象，有什么方便的方法呢？是否有关于从多个数组(可能超过 3 个数组)创建多层嵌套对象的文档？

我的努力...

arr1.forEach((item)=>{
    arr2.forEach((prop)=>{
        obj[item] = {}
        obj[item][prop] =  prop
    })
})

试试这个:

  var arr1 = ["a","b","c"];
  var arr2 = ["A","B","C"];
  var arr3 = [["aA","aB","aC"],["bA","bB","bC"], ["cA","cB","cC"]];
  var obj=[]; //initializing empty obj array
  for (i=0;i<arr1.length;i++){ // loop for creating outer objects
  var insideObj = {}, sampleObj={};
  for (j=0;j<arr2.length;j++) // loop for creating inner objects
    insideObj[arr2[j]]=arr3[i][j]; // creating inner objects like {"A":"cA","B":"cB","C":"cC"}
  sampleObj[arr1[i]]= insideObj; // assigning inner object as value of outer object
  obj.push(sampleObj); // pushing outer object to my obj array
}
