What happens when returnThis.label is referenced? Can one give me an example of how this might be used?
returnThis = {
'label' : aLabel ? this.value : false
};

A:
This makes use of ternary syntax.
aLabel ? this.value : false means: if aLabel is truthy (true, 1, "a", etc.), evaluate to this.value. Otherwise, evaulate to false.
The code is equivalent to the following:
returnThis = {};
if(aLabel) {
returnThis.label = this.value;
} else {
returnThis.label = false;
}

sorry. The usage of var newVAr=returnThis.label, will result in newVar having this.value if returnThis.label happens to be true?

A:
Nothing happens (it just gets the value). The statement: aLabel ? this.value : false has already been executed.
