Why do three React increment calls add only one?
KitForma editorial guide. Three setCount(count + 1) calls within one handler use the same snapshot.
Step-by-step answer
Three
setCount(count + 1) calls within one handler use the same snapshot. Queue functional updates instead: setCount(n => n + 1) three times. Each updater receives the preceding queued result. Keep updater functions pure because development checks may invoke them again. Verify an initial value of 4 becomes 7 with one click; do not send analytics or network writes from the updater.Sources and verification
