Creating Object Properties in JSON (Javascript) Dynamically in a Method

Question

I am left scratching my head here. I am pretty new with both JSON and Javascript so I am wondering how I would go about this.

Say I have an object:

MyObject.prototype = {
    // different methods and properties
    _randomMethod: function MyObject_randomMethod() {
         MyObject.myArray = [];
    },
};

How do I declare an array property for my object (like above: MyObject.myArray = [];) and have it available throughout the object so I can access it in other methods.

Maybe this has already been covered and I am just not using the right terminology but if someone could help me out, I'd appreciate it since I can't figure it out myself.

Just so its clear, I want to declare this array property dynamically within a method like the example above and then be able to use it in other methods within this same object with the 'this' reference or something similar.

Use this to refer to the current instance:

MyObject.prototype = {
    // different methods and properties
    _randomMethod: function MyObject_randomMethod() {
         this.myArray = [];
    },
};
