在数组中指定级别时转换对象列表 [英] Convert list of Objects when the levels are given in an array

问题描述

假设我有一个数组，该数组告诉我标签列表以及将它们添加到JSON对象中所需的值.您如何改变它?

Suppose I have an array which tells me the list of labels and a value that I need to add them into a JSON object. How do you transform it so?

所以基本上我有一个数组和一个值100

So basically I have is an array and a value 100

arr = ["1", "Male"]

应该这样将其转换为对象.

Should be transform it into a object as so.

obj = {
    "1":{
        "Male":100
        }
    }

推荐答案

您可以使用

You could use reduceRight for this. Use value as the initialValue of reduce and create a new level of nesting in every loop.

function createObj(paths, value) { 
  return paths.reduceRight((r, key) =>  ({ [key] : r }), value)  
}

console.log(createObj(["1", "Male"], 100))
console.log(createObj(["level 1", "level 2", "level 3" ], "value"))
