Extend native JavaScript array

Question

Is there any way to inherit a class from JS native function?

For example, I have a JS function like this:

function Xarray()
{
    Array.apply(this, a

With purpose to overcome the problem of extension of the native Array class, I took advantage of a decorator.

function extendArray(constructor: Function) {
    Object.getOwnPropertyNames(constructor.prototype)
        .filter(name => name !== 'constructor')
.forEach(name => {
    const attributes = Object.getOwnPropertyDescriptor(constructor.prototype, name);
    Object.defineProperty(Array.prototype, name, attributes);
  });
}

@extendArray
export class Collection extends Array {
  constructor(...args: T[]) {
    super(...args);
  }
  // my appended methods
}

BTW This decorator can be made more generic (for other native classes) if to use a decorator factory.
