Are all functions actually methods in javascript?

I am confused. Every function that is ever called in Javascript is called by some object. If I invoke it like this: b(); then this means that my global object invoked it: global.b();. So, all of them are methods, right? Why do we call them functions then?

Because a method is a function.

Function definition:

A "subroutine" that returns a value

Method definiton:

A callable member of a object
=> A function of a object

So you could say:

class Method extends Function

In Javascript every function returns a value, if it doesn't it returns undefined. Which makes it return something.

But the real answer is: Does it even matter? I'm going to cite the resource from the software engineering stack: "The point is, none of this is really consistent. It simply reflects the terminology employed by whatever languages are en vogue at the time."
