Welcome @muzhaqi16, and thanks for the pull request.

require('fs/promises') and require('fs').promises are equivalent. I'm going to close this, but if you think the change should be made, please explain in a comment and we can reopen it.

Error: Cannot find module 'fs/promises'
Require stack:

My node version is v12.18.3
