What is Prefetching?
Loading resources in advance before the user actually requests them to make navigation feel instant.
Why It Matters
Prefetching makes your app feel faster by having content ready before the user clicks a link.
Real-World Example
When hovering over a navigation link, the browser starts loading that page so it appears instantly when clicked.
“Understanding terms like Prefetching matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
