I think there are some errors in the final solution code, as it doesn't do what you describe.

Were you aiming at something like this?

var generated = function(value) { return new Function( "return (" + function(valueToSwap) { return { prop: valueToSwap }; } + ")(" + value + ");" ); };

It's called "regression analysis". Nothing to see here, move along. :)

I don't get it, what is?

Using a data set to create a function able to produce that data set.
