Change Detection

Adjusting change detection settings allows big improvements for Performance.

• Change detection means: detect / analyse changes, to identify if a component needs to be re-drawn

Settings on component:

changeDetection: ChangeDetectionStrategy.OnPush

• This means: don't perform change detection if @Input()s are not changed
