When answering any Angular question, the Decoded Frontend approach suggests structuring your answer in three layers: : What the feature does. The Problem : What real-world issue it solves.

With the complete shift away from NgModules, standalone components and performance metrics dictate modern Angular standards. Standalone Components

Switching a component to ChangeDetectionStrategy.OnPush instructs Angular to skip checking that component and its children unless explicit criteria are met. An OnPush component only re-renders when:
