Javascript 通过关键点将平面对象转换为嵌套结构

Javascript中有没有推荐的方法可以解析对象的键以将其转换为嵌套的内容？以下是一个例子：

将此转换为：

{
  "person[profile][0][degree_type]": "Bachelor's",
  "person[profile][0][college_name]": "AI Miami International University of Art and Design",
  "person[profile][0][business_school_name]": "",
  "person[profile][0][law_school_name]": "",
  "person[profile][0][other_school_name]": "",
  "person[profile][0][undergraduate_major_name]": "Anthropology",
  "person[profile][0][max_gpa]": "",
  "person[profile][1][degree_type]": "",
  "person[profile][1][college_name]": ""
}

为此：

"person": {
  "profile": [
    {
      "degree_type": "Bachelor's",
      "college_name": "AI Miami International University of Art and Design",
      "business_school_name": "",
      "law_school_name": "",
      "other_school_name": "",
      "undergraduate_major_name": "",
      "max_gpa": ""
    },
    {
      .....
    }
  ]
}

使用ES5和方法，您可能会遇到以下情况：

var data = {
  "person[profile][0][degree_type]": "Bachelor's",
  "person[profile][0][college_name]": "AI Miami International University of Art and Design",
  "person[profile][0][business_school_name]": "",
  "person[profile][0][law_school_name]": "",
  "person[profile][0][other_school_name]": "",
  "person[profile][0][undergraduate_major_name]": "Anthropology",
  "person[profile][0][max_gpa]": "",
  "person[profile][1][degree_type]": "",
  "person[profile][1][college_name]": ""
};

var object = Object.keys(data).reduce(function(result, item) {
  var o = result;
  var leaf = item.match(/\w+/g).reduce(function(current, next) {
    o[current] = o[current] || (String(next >>> 0) === next ? [] : {});
    o = o[current];
    return next;
  });
  o[leaf] = data[item];
  return result;
}, {});
