Using JSON.stringify in conjunction with TypeScript getter/setter

Question

I am using getter/setter accessors in TypeScript. As it is not possible to have the same name for a variable and method, I started to prefix the variable with a lower dash,

Answer 1

I think iterating through the properties and string manipulating is dangerous. I would do using the prototype of the object itself, something like this:

public static toJSONString() : string {
    return JSON.stringify(this, Object.keys(this.constructor.prototype)); // this is version class
}
