Say if all users are authorized using age as a parameter:

every.ts

const ageUser = [
  {
    name: "Jane Dow",
    age: 39,
  },
  {
    name: "John Doe",
    age: 39,
  },
  {
    name: "Rebecca Flex",
    age: 16,
  },
];

const authorizedUser = (valueGet) => valueGet.age >= 18;
const adductOnly = ageUser.every(authorizedUser);
console.log(adductOnly);
