An example of an AI chatbot conversation about change detection in Angular.
What is change detection in Angular?
Change detection in Angular is a mechanism that determines when to update the view in response to changes in the model.
How does Angular's change detection work?
Angular uses a hierarchical tree of components and checks for changes in the model using a strategy called Zone.js.
What are the different change detection strategies in Angular?
There are two main strategies: Default and OnPush. Default checks all components, while OnPush only checks when input properties change.
Can you explain when to use OnPush strategy?
Use OnPush when your component's inputs are immutable or when you want to optimize performance by reducing checks.
