使用方法

返回一个没有 undefined 属性的新对象。请注意，非可枚举键永远不会被删除。

import * as _ from "radashi";

const options = _.shake({
  mode: "party",
  volume: undefined,
  dancing: false,
  snacks: null,
});
// => { mode: 'party', dancing: false, snacks: null }

自定义条件

如果您将函数作为第二个参数传递，只有返回 false 的属性才会包含在结果中。

import * as _ from "radashi";

const options = _.shake(
  {
    mode: "party",
    volume: undefined,
    dancing: false,
    snacks: null,
  },
  (value) => !value
);
// => { mode: 'party' }
