⚡ Bolt: [performance improvement] - #749
Conversation
Refactored `useNaverTourismMarkers.ts` to replace multiple chained `.map()`, `.filter()`, and spread `[...arr]` operations with single-pass `for...of` loops. This avoids creating unnecessary intermediate arrays and significantly reduces garbage collection pressure during tight React render/effect loops when manipulating the Naver Map viewport markers.

💡 What: Refactored
useNaverTourismMarkers.tsto eliminate multiple intermediate array allocations (from chained.map().filter()and array spreads) during the marker reconciliation loop. These were replaced with single-passfor...ofloops and explicit arrays/Sets/Maps assignment.🎯 Why: During frequent map interactions like panning and zooming, the marker materialization hook recalculates visibility. Creating intermediate arrays on every viewport change increases garbage collection (GC) pressure and causes jank in the main thread.
📊 Impact: Reduces intermediate O(N) memory allocations during marker batch operations to O(1) extra space complexity, improving rendering frame rates during map viewport interactions.
🔬 Measurement: Profile the React application using Chrome DevTools Performance tab while rapidly panning the map with tourism markers enabled; memory allocation spikes and minor GC pauses should be noticeably reduced.
