Currency exchange app HELP

Hey, guys, unexperienced coder here. As a part of a side course I am building the currency exchange app with exchange rates updates via freeexchange. And I stumbled upon two questions:

  1. I have a mistake saying “Uncaught SyntaxError: Unexpected token :” when I try to console.log received json.
  2. I have no idea what to do next. I mean, I console.log(json) and then what? How do I extract necessary data out of this response? Do I need to do it?
    Converter itself -
    Money.js (necessary) -
    Codepen/Plunker won’t do because they don’t allow to do https to http requests.
