 const currentFavoritNumber = contract.retrieve();
  console.log(currentFavoritNumber);

There is no output currentFavoritNumber????? Can you tell me why?
Thank you all,I found the mistake, Correct spelling:
const currentFavoritNumber =await  contract.retrieve();
  console.log(currentFavoritNumber);

@Longmao1211 Process.exit(0). p should be small.

  .then(() => Process.exit(0)) //here spelling mistake.
  .catch((error) => {

    process.exit(1);
