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.

Default: 1

Use the default CheckAlways strategy, in which change detection is automatic until explicitly deactivated.
