Suspense boundaries define where your app shows fallback UI. But placing them wrong causes layout shifts, flash-of-loading, or waterfall fetches. This talk builds intuition for where boundaries belong and why getting it wrong makes everything feel slower.
Amazing stuff!
This talk was eye-opening. Never thought about Suspense placement like that.
The waterfall fetch demo really drove the point home.
Would love to see a follow-up on nested Suspense patterns.
