What counts as false
When Javascript is casting to a boolean, eg in an if statement, it treats as false the following values:
null
undefined
""
0 (or any number equivalent to 0 eg -0, 0.0 etc, or a string that represents such a number)
NaN
So !value will be true if value is any of the above.
What can't take a property setting or index
It's an error to try to set or get a property (with .) or an index (with []) on a null or undefined value.
