Get name of function in typescript

Question

I was looking for a way to get name of function passing in parameter

console.clear();
class A{
   test(){


   }
   testCall(fnc:Function){
     console.log(fnc.name); // i want it display test here not empty
     console.log(fnc);

   }
}

var a=new A();
a.testCall(a.test);

you can check this in jsbin http://jsbin.com/loluhu/edit?js,console

Have a look at this http://stackoverflow.com/questions/332422/how-do-i-get-the-name-of-an-objects-type-in-javascript It explains that although there is no real reflection in javascript, you can still use some workarounds but they are not very robust. — zoubida13, May 20 '16 at 08:34

You can extend the Function interface as follows:

interface Function {
    name: string;
}

function foo() {}
alert(foo.name);

See here for a fuller explanation.
