Script Preparation code:

let o, m, w;
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));
}

let o, m, w;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'];
o = obj['M'];
Map
m = map.get('M');
m = map.get('M');
Map in WeakMap
w = wm.get(data).get('M');
w = wm.get(data).get('M');
