You can use Array.prototype.filter()

filter()方法创建一个新数组，其中包含所有通过提供的功能实现的测试的元素.

The filter() method creates a new array with all elements that pass the test implemented by the provided function.

和 Array.prototype.includes()

includes()方法确定数组是否包含某个元素，并在适当时返回true或false.

var arr1 = [1, 3, 4,];

var arr2 = [
  {
    id: 1,
    title: 'Title 1',
   },
  {
    id: 2,
    title: 'Title 2',
   },
];

var res = arr2.filter(i => arr1.includes(i.id));

console.log(res);
