What is data prefetching and how can I implement it?
Data prefetching is a technique used to improve data retrieval performance by loading data before it's actually needed. You can implement it by analyzing access patterns and predicting which data will be needed next.
Can you give me an example of how to implement data prefetching in a web application?
Sure! In a web application, you can use the Fetch API to prefetch data when a user hovers over a link. This way, when they click, the data is already loaded.
What are the benefits of using data prefetching?
The main benefits include reduced latency, improved user experience, and efficient use of network resources.
Are there any downsides to data prefetching?
Yes, potential downsides include increased bandwidth usage and the risk of fetching unnecessary data, which can lead to wasted resources.
