Is it possible to exclude certain fields from being included in the json string?

Answer 1

abstract class Hideable {
    public hidden = [];
    public toJSON() {
        var result = {};
        for (var x in this) {
            if(x == "hidden") continue;
            if (this.hidden.indexOf(x) === -1) {
                result[x] = this[x];
            }
        }
        return result;
    };
}
