Do you mean that you are having trouble with the defaults?

Omitting maxRetransmits will result in nullptr in C++, null in Java,
and undefined in JavaScript, unless you specify it as:

dictionary blah {
  (double or Range) maxRetransmits? = null;

In which case the JavaScript value changes to null.  That is
unnecessary.  Define it as:

dictionary blah {
  (double or Range) maxRetransmits;

Then leave the language bindings to do their magic.  Yes, that means
that  { maxRetransmits: null } is an invalid constraint.  That's a
good thing.
