Why console.trace() result end at an "anonymous function"? What is that function?

If I run the code in the Javascript Console of an browser such as Chrome:

function foo() {
  function bar() {
    console.trace();
   }
   bar();
}
foo();

The result will be:

bar
foo
(anonymous function)

The console.trace() may trace to 'global scope' at the end. I know the global in the browser is the window object. But what is the specific function that (anonymous function) points to in the result?

Its expecting an anonymous function as argument. 

function Vinoth(){console.log("Vinoth")}
undefined

console.trace(Vinoth());
VM129:1 Vinoth
