I type fast into a search box and the results flash the wrong thing for a second because an older request answers after a newer one.
What you'll have at the end
A search handler where only the response for the most recently typed query ever updates the screen
You need
A search input already wired to call fetch on each keystroke or after a debounce, awaiting the response and writing whatever comes back straight into the results state, with nothing checking which query it actually belongs to.
Not covered
Cutting the number of requests sent in the first place, through debouncing or throttling, isn't covered here: that lowers how often two requests overlap, but doesn't stop it, so this recipe still holds even after that fix is in place.
Leans on
Debounce a search input to stop firing one request per keystroke
cuts down how many requests fire in the first place; pair the two when keystroke volume is also a problem, since debouncing alone doesn't fix reply ordering
Turn a failed fetch request into a message the user understands
for shaping what a genuine, non-cancelled fetch failure actually says to the user once this recipe has already told it apart from a cancellation
