vue 如何取消这段代码ESlint的报错

Question

 const map = permission.reduce((r, i) => (r[i.id] = true, r), {})
 const permissionId = menuList.filter(i => !!map[i.id]).map(i => i.id)

Unexpected use of comma operator.

这里是另一种写法↓

let permissionId = []
  for (const i in menuList) {
    for (const j in permission) {
      if (menuList[i].id == permission[j].id) {
        permissionId.push(menuList[i].id)
      }
    }
  }

Answer 1

你的意思是查找相同id把

let menuId = menuList.map(item=>item.id);
let permissionId = permission.filter(item=>menuId.includes(item.id)).map(item=>item.id);

Answer 2

onst map = permission.reduce((r, i) => {
        r[i.id] = true;
        return r;
    }, {});
