What are the main challenges of prefetching in web development?
Prefetching can lead to increased bandwidth usage, cache pollution, and may not always improve performance.
Can you explain what cache pollution means?
Cache pollution occurs when prefetching loads unnecessary data into the cache, evicting useful data and degrading performance.
How can developers mitigate these challenges?
Developers can use heuristics to predict user behavior, limit prefetching to critical resources, and monitor performance impacts.
Are there any tools to help with prefetching strategies?
Yes, tools like Google Lighthouse can analyze performance and suggest optimizations for prefetching strategies.
