Question

Can some one explain me what can be use case of function’s name property in Javascript?, I read that it can be helpful in recursion, how ?

function foo() {}
foo.name; // "foo"

Answer 1

a use case from MDN

You can use obj.constructor.name to check the “class” of an object

function a(){
}

var b = new a();
alert(b.constructor.name); //Alerts "a"

Think of it the as using get_class() in PHP or .getClass().getName() in Java.
