How to call Javascript function inside its own class?

Question

I am creating a Javascript class like so:

function Board(){
    this.initializePositionArray=function(){
        var tempPositionArray=[];
        tempPositionArray[0][0]="x";
        return tempPositionArray;
    };
    this.positionArray=initializePositionArray();
}

My aim is to initially fill positionArray with values using initializePositionArray(). However, the call to initializePositionArray() gives the following error:

Uncaught ReferenceError: initializePositionArray is not defined

You have to call it with this:

this.positionArray=this.initializePositionArray();

Because it is a property of your constructor and you were calling it as a global function which is not defined.

@Rajesh, is it actually a duplicate? I am defining my object in a different way than in the proposed duplicate question. – sigil May 09 '17 at 07:48
@sigil Its not about how you define the object. At the end you want to call a method inside same object. Yes accepted answer is not the desired answer but other answer addressed it correctly – Rajesh May 09 '17 at 07:49
