What are some effective data preloading techniques?

Data preloading techniques involve loading data before it's needed to improve performance. Common methods include eager loading, lazy loading, and caching.

Can you explain eager loading and lazy loading?

Eager loading fetches all the required data upfront, while lazy loading retrieves data only when it's needed, saving resources.

What are the benefits of using caching in data preloading?

Caching stores frequently accessed data in memory, reducing load times and server requests, which enhances user experience.

Are there any downsides to these techniques?

Yes, eager loading can lead to unnecessary data retrieval, while lazy loading may cause delays if data isn't preloaded when needed.
