Here's a function to convert map object to data object.

const xah_map_to_obj = ((xiterable) => {
  const xout = {};
  for (let [k, v] of xiterable) xout[k] = v;
  return xout;
});

// HHHH------------------------------
// test
const xx = new Map([["a", 3], ["b", 4]]);
const jj = xah_map_to_obj(xx);

console.log(jj);
// { a: 3, b: 4 }
