別の配列から重複しない値の配列を作り直したい

Last updated at Posted at 2022-01-11

配列A と配列Bにそれぞれ値があるが、配列Aに
含まれる値を
取り除いて配列Bを作り直したい

const list = [
  {
    id: 'f7747f80-9386-11eb-89b0',
  },
  {
    id: 'r7747f80-9386-11eb-89b0',
  }
];

const list2 = [
  {
     id: 'f7747f80-9386-11eb-89b0',
  },
  {
     id: 'a7747f80-9386-11eb-89b0',
  }
];


const targetList = list2.filter(o => !list.find(o => o.id === list2.id));

console.debug(1, targetList);

const allList = [...list, ...targetList]

console.debug(2, allList);
