No problems for the error :P.
Anyway I know Typescript's approach but I prefer something like:
```js
class Example {

    constructor(this.{foo, #bar}) {
    }
    showFoo() {
        console.log(e1.foo);
    }
    showBar() {
        console.log(e1.#bar);
    }
}
const e1 = new Example("answer", 42);
e1.showFoo(); // "answer"
e1.showBar(); // 42
```

To both declare, if not already declared, and initialize public and
private properties.
