When should I use lazy loading instead of eager loading?

When should I use lazy loading instead of eager loading?

Lazy loading is best when you want to improve performance by loading resources only when needed. Eager loading is useful when you need all data upfront.

Can you give me an example of each?

Sure! For lazy loading, think of images on a webpage that load as you scroll down. Eager loading would be preloading all images at once when the page loads.

What are the performance implications of each?

Lazy loading can reduce initial load time and save bandwidth, while eager loading can lead to faster access to data but may increase load time.

Are there any scenarios where eager loading is preferred?

Yes, eager loading is preferred when you know you'll need all the data immediately, like in a dashboard displaying all metrics at once.
