Duplicated track functions created

[shaqtsui]

Each time extendedFunction invoked, a new track function (line 73) is created to wrap previous one. This is cause the call stack very long after many times invoke.
Below is the call stack after 10 times invoke:

(anonymous function) (ShowcaseCtrl.js:4)
originalFunction (extendFunction.js:77)
originalFunction (extendFunction.js:77)
originalFunction (extendFunction.js:77)
originalFunction (extendFunction.js:77)
originalFunction (extendFunction.js:77)
originalFunction (extendFunction.js:77)
originalFunction (extendFunction.js:77)
originalFunction (extendFunction.js:77)
originalFunction (extendFunction.js:77)
(anonymous function) (angular-requirejs.js:10)
extendedFunction (extendFunction.js:103)

That is indeed what happens, do you know of a way to prevent this? Can you group your function extensions into fewer calls, or do you think the library should do this? In chrome the library could increase the number of functions in the stack trace to 20 instead of 10

I also need to document a new style of extending browser defined methods that doesn't require extendFunction.js

alert = message => {
  if ($('#alert').length)  {
    $('#alert').text(message).show()
  } else {
    Window.prototype.alert.call(window, message)
  }
}

Can we introduce a property as an indicator to see whether this func already enhanced?
