Script Preparation code:

window.basic = {a : 1, b: 2};
window.proxy = new Proxy({a : 1, b: 2}, {get : (t, p) => t[p]})
window.proto = Object.setPrototypeOf({}, {a : 1, b: 2})

Tests:

Basic
let a = basic.a; let b = basic.b;
Proxy
let a = proxy.a; let b = proxy.b;
Proto
let a = proto.a; let b = proto.b;
