Script Preparation code:

class Signal {
  constructor(state) {
    this.value = state;
  }

  get() {
    return this.value; 
  }
  set(newValue) {
    if (newValue !== this.value) {
      this.value = newValue;
    }
  }
}

function createSignal(value) {
  const v = new Signal(value);
  return [v.get.bind(v), v.set.bind(v)];
}
var [sigData, setData] = createSignal({
    value: 'data'
});
var mObject = {_value:'data'};
Object.defineProperty(mObject, 'value', {
    set: function (nv) {
        this._value = nv;
    },
    get: function() {
        return this._value;
    }
});
var object = {
    value: 'data'
};
var proxy = new Proxy(object, {})
var proxyWithHandler = new Proxy(object, {
    get(target, prop, receiver) {
        return Reflect.get(target, prop, receiver)
    }
})
