Why does changing a nested React object fail to refresh the view?
KitForma editorial guide. Mutation preserves references React may use to skip work.
Step-by-step guidance
Mutation preserves references React may use to skip work. Copy every changed level:
setProfile(p => ({...p, address: {...p.address, city: "Bursa"}})). A shallow copy of profile followed by mutating its old address still changes shared data. Verify the previous snapshot’s city remains unchanged and a memoized address child updates. For deeply nested models, flatten state or use a deliberate immutable-update library.Sources and verification
