算法求助:JS 模拟 cantains 匹配

数组a 是一维数组
["a","b","c"]
数组b 是二维数组
[[{"id":"1"},{"id":"2"},{"id":"a"}],[{"id":"b"}],[{id:"c"}]]

要求

b 的所有元素如果匹配上 a 里的元素的 id,就给 b 这项增加属性,is_checked 反之是 false。

    var a = ['a', 'b', 'c']
    var b = [
      { id: 'a' },
      { id: 'd' },
      { id: 'e' },
    ]

    function cantains (one, two) {
      two.forEach(item => {
        item.is_checked = a.some(id => id === item.id)
      })
      return two;
    }
