What are the different change detection strategies in Angular?

In Angular, there are two main change detection strategies: Default and OnPush. Default checks all components, while OnPush only checks when input properties change.

When should I use OnPush strategy?

You should use the OnPush strategy when your component's inputs are immutable or when you want to optimize performance by reducing checks.

Can you give an example of using OnPush?

Sure! If you have a component that receives an object as an input, and you only update that object reference when it changes, you can use OnPush to avoid unnecessary checks.

What are the performance implications of using Default strategy?

Using the Default strategy can lead to performance issues in large applications, as it checks all components in the tree, even if they haven't changed.
