Get anonymous function name

Question

How to get the the variable name from within a function in this example:

// it should return A
var A = function(){ console.log(this.name); } 

Is there something like this?

Answer 1

That function is anonymous; it has no name. You could, however, give it a name:

var A = function a() {};

Then its name is accessible via Function.name:

var A = function a() {};
A.name
> 'a'
