Script Preparation code:

data1 = {};
data2 = {};
data3 = {};

handler1 = {
  get: (target, prop) => (target[prop]),
  set: (target, prop, value) => (target[prop] = value),

};

proxy2 = new  Proxy(data2, handler2);

  set: (target, prop, value) => (console.error("IMMUTABLE!!!")),
};

proxy3 = new  Proxy(data3, handler3);

data4 = {
  get test() {
    return this._test;
  },

    return this._test = value;
  }
