In JavaScript function is object and has all properties which belong to objects. So all of them you see in your console line.

Short description:

name :'' - anonymous function in your case name of function is empty

caller:null function that call your function

arguments: null all arguments which were passed into function

You need take a look at Inheritance of JS

but why is that infinite repetition inside the prototype Object?

An Object's .constructor property will usually reference a Function,
Functions are objects, which inherit from a prototype object.
The prototype object from which functions inherit has a .constructor property.
