javascriptScope errorMedium

Variable not found in scope

Time: 0:00

What it should do

finalPrice(price, isMember) should apply a 10% discount for members and return the price to pay.

What goes wrong

Every call throws: ReferenceError: discounted is not defined.

Hints

This is a scope and closure bugs bug

Every callback reports the last value, a counter never increments, UnboundLocalError on a variable you can see.
