Pattern: Missing use of ChangeDetectionStrategy.OnPush

Issue: -

Description

By default Angular uses the ChangeDetectionStrategy.Default.

This strategy doesn’t assume anything about the application, therefore every time something changes in our application, as a result of various user events, timers, XHR, promises, etc., a change detection will run on all components.

By using ChangeDetectionStrategy.OnPush, Angular will only run the change detection cycle in the following cases:

• Inputs references change.
• An event originated from the component or one of its children.
• If manually called.
