@theghostyced thanks for the feedback. Please What do you think is a better implementation?

Well I would have expected you to send your response in a JSON obj

{ 
          message: 'Lorem Ipsum',
          user: { userName: 'Ekpang' }
 }

so you could then call the data as data.message or data.user.userName
But it all good though. Nice one

Looks good to me
