What's the fundamental difference between how React and Vue update the UI? How does that affect how you deal with unnecessary re-renders?

~4 min by voice

How to approach it

The interviewer checks whether you understand the mechanics of UI updates in each framework: React re-renders the subtree by default, while Vue tracks dependencies precisely. And whether you can derive specific optimization techniques from that understanding instead of applying memoization blindly.
