What is the difference between Default and OnPush change detection strategies in Angular?

What is the difference between Default and OnPush change detection strategies in Angular?

In Angular, the Default strategy checks for changes in all components, while OnPush only checks when input properties change or events occur.

When should I use OnPush instead of Default?

You should use OnPush when your component relies on immutable data or when performance is a concern, as it reduces unnecessary checks.

Can you give an example of when Default might be better?

Default is better for components that frequently change or rely on dynamic data, as it ensures all changes are detected.

What are the performance implications of using OnPush?

Using OnPush can significantly improve performance by reducing the number of checks Angular performs, especially in large applications.

Are there any downsides to using OnPush?

Yes, the downside is that you need to manage change detection more carefully, as it won't automatically detect changes unless inputs change.
