and (dependentKey) Ember.ComputedProperty
public
A computed property that performs a logical and
on the original values for the provided dependent properties.
You may pass in more than two properties and even use property brace expansion. The computed property will return the first falsy value or last truthy value just like JavaScript's &&
operator.
Example
let Hamster = Ember.Object.extend({ readyForCamp: Ember.computed.and('hasTent', 'hasBackpack'), readyForHike: Ember.computed.and('hasWalkingStick', 'hasBackpack') }); let tomster = Hamster.create(); tomster.get('readyForCamp'); // false tomster.set('hasTent', true); tomster.get('readyForCamp'); // false tomster.set('hasBackpack', true); tomster.get('readyForCamp'); // true tomster.set('hasBackpack', 'Yes'); tomster.get('readyForCamp'); // 'Yes' tomster.set('hasWalkingStick', null); tomster.get('readyForHike'); // null
