import { mapBy, min } from '@ember/object/computed';
import EmberObject from '@ember/object';

let Person = EmberObject.extend({
  childAges: mapBy('children', 'age'),
  minChildAge: min('childAges')
});

let lordByron = Person.create({ children: [] });

lordByron.get('minChildAge'); // Infinity
lordByron.get('children').pushObject({
  name: 'Augusta Ada Byron', age: 7
});
lordByron.get('minChildAge'); // 7
lordByron.get('children').pushObjects([{
  name: 'Allegra Byron',
  age: 5
}, {
  name: 'Elizabeth Medora Leigh',
  age: 8
}]);
lordByron.get('minChildAge'); // 5

If the types of the arguments are not numbers, they will be converted to numbers and the type of the return value will always be Number. For example, the min of a list of Date objects will be the lowest timestamp as a Number. This behavior is consistent with Math.min.
