Error? Why?

[qucumbah]

if you execute the code it throws:
ReferenceError: Must call super constructor in derived class before accessing 'this' or returning from derived constructor
the description even says "Here’s an example of such code (it doesn’t work – why? fix it?)"

Right, thanks!

[iliakan]

There was an error there indeed.
