javascript - 在另一个对象数组中过滤一个对象数组的最佳方法是什么？

Question

我有一个这样的数组:

     const array = [
       { 
         id: 1,
         list: [
          {
            name: "abc",
            quantity: 46,
          },
          {
            name: "abc cba",
            quantity: 8,
          },
         ]
       }
    
       { 
         id: 2,
         list: [
          {
            name: "def",
            quantity: 895,
          },
          {
            name: "abc ebn",
            quantity: 8,
          },
         ]
       }
     ]

如果我想检查该数组是否包含:name: "abc" 并仅过滤包含它的对象，过滤该数组的最佳方法是什么？

我试过在 filter() 中使用 map.()，但我不知道这样做是否合适。我的代码是这样的:

let filteredArray = array.filter(el => {

   let filteredName;

   el.list.map (name => {
      if (elt.name.includes("abc"){
        filteredName = name
       }
   }
 return filteredName;
})

const array = [
  { id: 1, list: [ { name: "abc", quantity: 46, }, { name: "abc cba", quantity: 8 } ] },
  { id: 2, list: [ { name: "def", quantity: 895, }, {  name: "abc ebn", quantity: 8 } ] }
];

// iterate over array
const res = array.map(({ list, ...el }) => (
  // filter current element's list
  { ...el, list: list.filter(({ name }) => name.includes("abc")) }
));

console.log(res);
