Default Parameters in JavaScript

you may have to check for null if you want to use a default arg2 while providing an explicit arg3. i guess you can always do:

    myfn('a',undefined,'b');

Yeah. You see that sometimes in modern JS, e.g. when pretty-printing JSON:

  JSON.parse(object, undefined, 2);
