const map = new Map();
const obj = Object.create(null);
const wm  = new WeakMap();
let data = Object.create(null);
wm.set(data, new Map());

for (let i = 65; i < 90; i++) {
  let t = String.fromCharCode(i);
  obj[t] = i;
  map.set(t, i);
  wm.set(data, (wm.get(data)).set(t, i));
}

Tests:

Object
o = obj['M'];
Map
m = map.get('M');
