What are the performance implications of different loading strategies?

Different loading strategies can significantly impact the performance of web applications. For instance, lazy loading can improve initial load times by only loading resources when needed, while eager loading may lead to faster access to all resources but can increase initial load time.

Can you explain lazy loading in more detail?

Sure! Lazy loading is a design pattern that postpones the loading of non-essential resources until they are actually needed. This can enhance user experience by reducing initial load times and saving bandwidth.

What are some common scenarios where lazy loading is beneficial?

Lazy loading is particularly beneficial in scenarios like image-heavy websites, infinite scrolling pages, and applications with many components that aren't immediately visible to the user.

Are there any downsides to using lazy loading?

Yes, while lazy loading can improve performance, it may also lead to a delay in loading content when users scroll or navigate, which can affect user experience if not implemented carefully.
