`OnPush: 0`	Use the `CheckOnce` strategy, meaning that automatic change detection is deactivated until reactivated by setting the strategy to `Default` (`CheckAlways`). Change detection can still be explicitly invoked. This strategy applies to all child directives and cannot be overridden.
`Default: 1`	Use the default `CheckAlways` strategy, in which change detection is automatic until explicitly deactivated.
