do something when function executes Jquery

Question

So I have a function that is recursive for inverting colors. Here is the code:

function invert(id,what){
    var color = $(id).css(what);
    var matchColors

I am not sure what your exact scenario is, but maybe you could override the function with a wrapper:

var invertOriginal = invert;
var counter = 0;

var invert = function(id, what, max) {
  invertOriginal(id, what, max); 

  // do counter stuff here, e.g.
  counter++; 
};
