Faster web navigation with predictive prefetching

Learn about predictive prefetching and how Guess.js implements it.

In my Faster Web Navigation with Predictive Prefetching session at Google I/O 2019, I began by talking about optimizing web apps with code splitting and the potential performance implications for subsequent page navigation. In the second part of the talk, I discussed how to improve navigation speed by using Guess.js to set up predictive prefetching:

Code splitting for faster web apps

Web apps are slow, and JavaScript is among the most expensive resources that you ship. Waiting for a slow web app to load can frustrate your users and decrease conversions.
