About
Instant.Page uses just-in-time preloading - it preloads a page right before a user clicks on it.
The Speculation Rules API is a browser API that improves navigation performance by prefetching or prerendering pages that users are likely to visit next.
It uses 
JSON-based rules embedded in 
HTML or HTTP headers, and is designed as a successor to older techniques such as 
Prefetch and the deprecated Prerender attribute.
