Optional function parameters

ramunas_k

Hi. Newbie here.

Does FeatureScript support optional function parameters?
If not I see two options:
Function overloads

function decrement(n is number) returns number
{
    return decrement(n, 1);
}
function decrement(n is number, amount is number) returns number
{
   return n - amount;
}

Passing undefined as optional parameter value
Should be possible but then how do I write a precondition if parameter is not undefined it should be of certain type.

Thanks

Overloads is the easiest way

The other option is to pass in a map of all parameters, but I agree with Neil that overloads is the best option.
