## Dot-Notation

Using the helper, you can retrieve the nested value using dot-notation:

```js
helper.get('one.two.three'); // Returns 4.
helper.get('one.two'); // Returns {three: 4}.
```

This dot notation can also be used be used when pushing nested values:

```js
dataLayer.push({
'one.two.three': 4
});
```

Pushed object keys will only be processed for dot-notation at the top level. Periods
in nested object keys will be treated literally, not as dot-notation.

Conflicting pushed keys will resolve to the sequentially last pushed value.

```js
dataLayer.push({
'one.two.three': 4, 'one.two': { 'three': 5 }
});
helper.get('one.two.three'); // Returns 5.
```

As mentioned above, the abstract data model is an internal representation, which holds
the most recent value for all keys that have been set by a dataLayer message. This
