What are the differences between lazy and eager loading in performance?

What are the differences between lazy and eager loading in performance?

Lazy loading loads data only when it's needed, while eager loading loads all data upfront. This can affect performance.

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

Sure! Lazy loading is great for images on a webpage, where you only load them as they come into the viewport.

What about eager loading? When is it beneficial?

Eager loading is beneficial when you know you'll need all the data upfront, like when displaying a complete report.

Are there any downsides to either approach?

Yes, lazy loading can lead to delays in data retrieval, while eager loading can consume more memory and resources upfront.
