They take the form:
function functionName(variableName: any): variableName is DesiredType {
// body that returns boolean
}
If the function returns true, TypeScript will narrow the type to DesiredType in any bl...

To compare the difference of two dates, we can do the comparison based on the timestamp.
var date1 = new Date();
var date2 = new Date(date1.valueOf() + 5000);
var dateDiff = date1.valueOf() - date2.valueOf();
var dateDiffInYears = dateDiff/1000/60/60/24/365; //convert milliseconds into years

There's an alternative formulation of the free monad called the Freer (or Prompt, or Operational) monad. The Freer monad doesn't require a Functor instance for its underlying instruction set, and it has a more recognisably list-like structure than the standard free monad.
The Freer monad represents...
