vargs

=====

> variable argument handling for functions taking a callback

rationale

----------

JavaScript has very poor argument handling. *vargs* tries to make it simpler.

synopsis

--------

    var Args = require("vargs").Constructor;

  

    function (/* [arg1, arg2, ...][,callback] */) {

        var args = new(Args)(arguments);

        

        args.first;    // first argument

        args.last;     // last argument before callback

        args.callback; // callback argument, or an empty function

        args.all;      // all arguments except callback

        args.length;   // number of arguments, not including callback

        

        args.callbackGiven(); // returns true or false

        args.at(-1);          // last argument, including callback

        args.array;           // all arguments, including callback

    }
