// @see https://github.com/NoriSte/recoil-apis

// core function, it requires the id
function logId(id: string) {
  console.log(id);
}

// create a new function that accesses the id thanks to its closure
function createLogid(id: string) {
  // pubklic functions, it doesn't require the id
  return function () {
    logId(id);
  };
}

// you can log the iod only if you know it
logId("1");

// higher-order function creation
const logIdWithoutKnowingIt = createLogid("1");
// you can log the id without knowing it
logIdWithoutKnowingIt();
