-// For one, the user variable in the line:
-// return user.delete().then(function() {
-// does not have a .delete function, it would need to be user.user.delete()
-// & in this example they suggest:
-// // Merge prevUser and currentUser data stored in Firebase
-// which in this auth context (& assuming basic security rules enabled) would mean you would only have access to currentUser ’s storage, 
-// but then they delete the current user & link the credential to the previous user. In otherwords you would only be able to merge the previous user’s 
-// data into the current user’s storage, however the current user is deleted & no longer accessible
-// So I’d just like a sanity check here that this example is indeed a flawed approach!
