What is Angular change detection and how does it work?

Angular change detection is a mechanism that allows Angular to track changes in the application state and update the view accordingly. It works by checking the component's data-bound properties and determining if they have changed.

Can you explain the different strategies for change detection in Angular?

Sure! Angular provides two main change detection strategies: Default and OnPush. Default checks all components, while OnPush only checks when input properties change or an event occurs.

How can I optimize change detection in my Angular application?

You can optimize change detection by using OnPush strategy, detaching change detection for certain components, and minimizing the number of bindings.

What are the common pitfalls to avoid with change detection?

Common pitfalls include not using OnPush when appropriate, creating too many bindings, and not understanding how async operations affect change detection.
