I'm starting with OO in JavaScript, and I have a class with the following methods:

```
 count(element) {
        return document.querySelectorAll(element).length;
}

 get(element, occurence) {
        return document.querySelectorAll(element)[occurence];
 }

```

The first method analyse how many elements of the specified type exist in the DOM and returns the numeric result, and the second works as a `querySelector()`, with some differences.

I would like to chain those methods with other methods. But as far as I know, methods must return `this` to be chained. How can I chain those methods?
