使用方法

同时应用过滤和映射操作，一次完成。 如果省略过滤器，返回所有非空值的映射值。

import * as _ from "radashi";

const fish = [
  {
    name: "Marlin",
    weight: 105,
    source: "ocean",
  },
  {
    name: "Bass",
    weight: 8,
    source: "lake",
  },
  {
    name: "Trout",
    weight: 13,
    source: "lake",
  },
];

_.select(
  fish,
  (f) => f.weight,
  (f) => f.source === "lake"
); // => [8, 13]
