Question

There is an object c.
It has a function c.log(message)

Is it possible to add some variables for using them like c.log.debug = true?

Answer 1

Javascript is a full object-orientated language. That means that almost everything is an object – even functions :

var f = function(){};
alert(f instanceof Function);
// but this statement is also true
alert(f instanceof Object);

// so you could add/remove propreties on a function as on any other object : 
f.foo = 'bar';

// and you still can call f, because f is still a function
f();
