Javascript function parameter hooker

hook.js

Function.prototype.getParameters = function () {
  return this.parameters || (this.parameters = /function *(?:.*?)\((.*?)\)/.exec(this + "")[1].split(/,/g).map(Function.prototype.call, String.prototype.trim));
} // https://gist.github.com/co3moz/b6bc4bbfa825b60c3812

Function.prototype.hook = function(t, o) {
   (o || (o = t, t = this));
   return this.apply(t, this.getParameters().map(function(p) { return o[p] }));
}

example

(function(myVariable, soAnotherOne) { console.log(myVariable, soAnotherOne); }).hook({soAnotherOne: 1, myVariable: 2});
// prints "2 1"

(function(soAnotherOne, myVariable) { console.log(myVariable, soAnotherOne); }).hook({soAnotherOne: 1, myVariable: 2})
// prints "2 1" too

we expect that all parameters hooked to object. even we change the order of parameters

example 2

function MyLibrary(callback) {
  return callback.hook({req: {..} res: {..}, next: (function() {..})});
}

MyLibrary(function(res) { // no need req
  res.send("ok");
});
