Thanks for sorting the placeholder, that works how I hoped now.

The idea was to do the refactoring to build up a class in stages: given a list of methods and attributes, a student will naturally try to do the whole thing at once, then get an error and give up. So you might have some options for what other methods they want to add, or to add a subclass, etc. It was a proof of concept really, as I think the same idea could be applied to other bits of code.

This was perhaps wishful thinking, but I was hoping that it might be possible to use the student's answer to the first explore mode part in the second, so that they could add to it.

Couple of things to look at in the programming extension when I tried this out:

• Noticed an issue in the marking of the steps:
  
  "Failed to execute 'postMessage' on 'DedicatedWorkerGlobalScope': [object Object] could not be cloned."
  
  
• The correct answer is actually the placeholder content I think?
