I have read the AWS Amplify API and I have found some weird thing.
I've found 2 similar functions
currentAuthenticatedUser() and currentUserPoolUser().
They have the same description, parameters, and returns.
I want to know why they separated.

https://aws-amplify.github.io/amplify-js/api/classes/authclass.html#currentauthenticateduser
https://aws-amplify.github.io/amplify-js/api/classes/authclass.html#currentuserpooluser
I believe user pool users are those that are from Cognito, whereas an authenticated user is one that come from an identity pool (from a federated identity).
See: https://aws.amazon.com/premiumsupport/knowledge-center/cognito-user-pools-identity-pools/
From the code, it looks like currentAuthenticatedUser checks for federation info. However, if it doesn't find federation info, it just calls currentUserPoolUser. So I'd say call currentUserPoolUser if you know you're never going to be using federated logins, but you should probably call currentAuthenticatedUser if there's a chance you might.
according to amplify auth docs, both result in "A promise resolves to current authenticated CognitoUser if success"
