请求帮助以了解&如何启动类的typescript数组

我错过了什么?

地图组件

• 如果不是,正确的方法是什么?

    // Initiate
    const response: Array<LatLngExpression> = []; // Seems to work
    const response: [LatLngExpression] = [];      // Msg: Type any[] is not assignable to type [any]
    // Add a value to the array
    response.push(geoPoint.getLatLng());

地质点

export clas GeoPoint {
  private _id: string;
  private _value: LatLngExpression; // This is a leaflet.LatLngExpression
  private _selected: boolean = false;

  constructor (id: string, latLng:LatLngExpression, selected?:boolean) {
    this._id = id;
    this._value = latLng;
    if(selected){
      this._selected = selected;
    }
  }

  set()... // you get the idea
  get()... // you get the idea
}
