function apiCall() {
  return new Promise(
    (resolve) => {
      setTimeout(() => resolve({ data: { test: "123" } }), 1000);
    },
    (reject) => {},
  );
}

async function caller() {
  return await apiCall().then((res) => {
    res.data;
  });
}

console.log(caller());

This call returns a pending promise. How can I wait in the caller function until the promise is ready and then return the value? I don't want to call await caller()
