Answer 1

使用简单的foreach循环:

first = [
  {
    Vitamins: [
      "Please explain details about vitamins.",
      "Vitamin is a vitamin.:P:D",
      "7"
    ]
  },
  {
    Vitamins: [
      "i need more explanation about VitaminD. bcoz i'm new to medicine field ",
      "i don't know the ans.. :P",
      "7"
    ]
  },
  {
    Minerals: [
      "i need more info about Minerals!",
      "Minerals are found in soils",
      "8"
    ]
  }
];
last = {};
for (var i in first) {
  if (typeof last[i] == "undefined")
    last[i] = [];
  last[i].push(first[i]);
}
console.log(last);
