Functions defined by function expressions and function declarations are parsed only once, while those defined by the Function constructor are not. We cannot perform any time series based operation on the dates if they are not in the right format. As json becomes more complex, the approaches for finding values inside of the json also become complex. That is, the function body string passed to the Function constructor must be parsed each and every time the constructor is called.
