### select
Retrieve a property indicated by the selector from an object.
Retrieve a set of properties indicated by the given selectors from an object.
If the property does not exists returns `undefined`.
Use `Array.map()` for each selector, `String.split('.')` to split each selector and `Array.reduce()` to get the value indicated by it.
```js
const select = (from, selector) =>
selector.split('.').reduce((prev, cur) => prev && prev[cur], from);
const select = (from, ...selectors) =>
[...selectors].map(s => s.split('.').reduce((prev, cur) => prev && prev[cur], from));
