__proto__: userProxy,

As per MDN and ECMASCRIPT, use of this approach seems to be deemed legacy and will at some point be withdrawn from browsers.

https://tc39.es/ecma262/multipage/fundamental-objects.html#sec-object.prototype.__proto__

The alternative seems to be Object.create ?

// considered bad practice
let admin = {
  __proto__: userProxy,
  _name: "Admin"
};

// recommended
let admin = Object.create(userProxy);
admin._name = 'Admin'
