I've got a Map<string, string> variable in typescript:

let m = Map<string, string>().set('tag', 'v1');

I want to convert to json string representation:

'{tag: v1}'

I've tried 3 different ways. First is to use m.toString(). Second is using JSON.stringify(m). Both returned {}. I've even tried to convert the Map to a javascript object first and then convert to string:

function MapToString(map): string {

  let ro = {};

  Object.keys(map).forEach( key => {

    ro[key] = map[key];

  });

  return JSON.stringify(ro);

}



s = MapToString(m);

This returned {} as well when I tried to print it in the console.
