Javascript OOP function printing as string

Trying to get my head around javascript OOP, why is this causing the test method to print the entire function definition as if it was a string?

var Myclass = function Myclass(){
    this.connection = make_ajax();
    this.hasConnection = function(){return this.connection};

    this.test = function(){
        console.log(this.hasConnection); 
    }
}
var x = new Myclass();
x.test();

Result:

log: function(){return this.connection}

When you

consloe.log(this.hasConnection);

you are logging the actual function, not the result of calling the function. Try changing this line to 

consloe.log(this.hasConnection());

Because... you're not calling the function. You're logging the function itself, and since logging requires a string it calls the built-in toString method which returns the function as a string.

Try console.log(this.hasConnection());
