group

将数组中的元素分类到不同的组中

使用方法

给定一个项目数组，group 将构建一个对象，其中每个键都是属于该组的项目数组。

import * as _ from "radashi";

const fish = [
  {
    name: "Marlin",
    source: "ocean",
  },
  {
    name: "Bass",
    source: "lake",
  },
  {
    name: "Trout",
    source: "lake",
  },
];

const fishBySource = _.group(fish, (f) => f.source); // => { ocean: [marlin], lake: [bass, trout] }
