我可以通过某种方式将Proxy分配给Number.prototype吗？

Question

Can I assign Proxy to Number.prototype somehow? I want to be able to call:

42..anyMethod

Answer 1

I just found the solution.

Object.setPrototypeOf(Number.prototype, new Proxy({}, {
  get(target, prop, receiver) {
    return prop in target || typeof prop === 'symbol' ? target[prop] : { target, prop, receiver };
  }
}));

No, this is not possible. The builtin prototypes are locked down, Number.prototype is not writable and even if it was then Number would still ignore it and construct objects with the builtin prototype.
