```
type Constructor<T> = new (...args: any[]) => T;
type Constructable = Constructor<{}>;

function Timestamped<TBase extends Constructable>(Base: TBase) {
    return class extends Base {
        timestamp = Date.now();
    };
}
```
Hoo boy I was sure worried that ES5 was getting too hard to parse…thank god we’ve found ways of making code more readable and useful without giving in to architecture astronauting!

EDIT:

Just to be clear, the article is good @mariusschulz. :)

I’m just annoyed at the ecosystem.
