The finally Method

Run cleanup code always

The .finally() method runs whether the promise fulfills or rejects. Use it for cleanup that should happen either way.

showSpinner();

fetchData()
  .then(displayData)
  .catch(showError)
  .finally(() => {
    hideSpinner(); // Always runs
  });

.finally() doesn't receive any arguments.
