select

Retrieve a property that indicated by the selector from an object.

If the property does not exists returns undefined.

const select = (from, selector) =>
  selector.split('.').reduce((prev, cur) => prev && prev[cur], from);

const obj = { selector: { to: { val: 'val to select' } } };
select(obj, 'selector.to.val'); // 'val to select'
