enum ChangeDetectionStrategy { OnPush: ChangeDetectionStrategy.OnPush; Eager: ChangeDetectionStrategy.Eager; Default: ChangeDetectionStrategy.Eager;}
OnPush
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.
NOTE: OnPush is enabled by default.
Eager
Use the Eager strategy, meaning that the component is checked eagerly when the change
detection traversal reaches it, rather than only checking under certain circumstances (e.g.
markForCheck, a signal in the template changed, etc).
Default
This value is equivalent to setting Eager and is due to be removed.
