Answer 1

The issue is that writable and set/get are mutually exclusive. The code generates this helpful error in Chrome:

Invalid property. A property cannot both have accessors and be writable...

This makes some logical sense: if you have set/get accessors on a property, that property is never going to be written to and/or read from, because any attempts to read/write it will be intercepted by the accessor functions. If you define a property as writable and give it accessor functions, you are simultaneously saying:

1. "The value of this property can be directly altered," and
2. "Block all attempts to read and/or write to this property; instead, use these functions."

The error is simply stopping you from specifying a contradiction. I assume from the fact that you wrote a getter and setter, you don't really want the property to be writable. Just remove that line, and your code runs perfectly.
