Object.defineProperty on a prototype prevents JSON.stringify from serializing it

Question

I\'m using TypeScript to define some classes and when I create a property, it generates the equivalent to Class1 in the following plunkr:

As you've discovered, it won't serialize properties defined on prototype.

I know it's not ideal, but another option is to do this:

class Class1 {
    private _name = "test1";

    Name: string; // do this to make the compiler happy

    constructor() {
        Object.defineProperty(this, "Name", {
            get: function() { return this._name; },
            set: function(value) { this._name = value; },
            enumerable: true
        });
    }
}

Defining the property on the instance will serialize the property.
