To do array with object sorting with JavaScript Underscore sortBy, we call sortBy with the array and a callback to return the field to sort by.

For instance, we write

const sorted = _.sortBy(arr, (o) => {
  return o.start.dateTime;
});

to call sortBy with arr and a callback that returns the start.dateTime property from the object to sort by this property.

An array with the sorted objects is returned.
