I'll have to agree here. Maybe the dev tools are way ahead of the course but it's really tedious to follow at times. For instance, in 4.2 I'm supposed to call Calendar.createEvent() method from the console to see "that we get the same exception."
Matter of the fact is doing that results in a "VM5073:1 Uncaught ReferenceError: Calendar is not defined(…)" error. I have no idea what I'm doing wrong. The question however passes if I press the Create Event button in the app.
Last instruction is "type $("#events .event") in the console to see an array with the current list of events." Doing this results in a "null" return and the question won't pass. Again, I have no idea what I'm doing wrong if anything.
This is in addition to downloading the Chrome extension and it initially just passing the first question in every section automatically.
For a newbie like me this is really disheartening because I get no input on what I'm doing wrong.
