How to get property outside of class?

I have a class:

export class MapApi {
  [reonMap]: Map;

constructor(container: HTMLElement, props: nMapProps = {}) {
    this[Map] = new Map(container, libraryUrl, props);
  }

}

How to get instance this[Map] of new Map outside class?

TypeScript supports getters/setters as a way of intercepting accesses to a member of an object. In your class, this can be implemented as follows:

export class MapApi {
    private _reonMap: Map;

    constructor(container: HTMLElement, props: nMapProps = {}) {
        this._reonMap = new Map(container, libraryUrl, props);
    }

    get reonMap(): Map {
      return this._reonMap;
    }
}

To access it outside of the class, do the following:

const mapApi = new MapApi(...);
const reonMap = mapApi.reonMap;
