Answer
React processes updates in an ordered queue using lane priorities to maintain determinism.
Quick Answer
React processes all queued updates in the same batch atomically before committing to the DOM. It uses the work-in-progress tree to compute the full result of all updates, then commits the final tree in one synchronous pass. Users never see intermediate states — the DOM goes from one consistent state to the next.
