What are the best practices for eager loading in web development?

Eager loading is a technique to load related data upfront to improve performance. Best practices include using it when you know you'll need related data, minimizing the number of queries, and ensuring it doesn't load unnecessary data.

Can you give me an example of when to use eager loading?

Sure! If you're displaying a list of blog posts along with their authors, eager loading the authors' data with the posts can reduce the number of database queries.

What are the potential downsides of eager loading?

The main downside is that it can lead to loading too much data, which may increase memory usage and slow down response times if not managed properly.

How does eager loading compare to lazy loading?

Eager loading fetches all related data upfront, while lazy loading retrieves data only when it's needed. Eager loading can improve performance in certain scenarios, but lazy loading can save resources when related data isn't always required.
