💡 What: Optimized the array lookup in$O(N \cdot M)$ time complexity. With thousands of items, this was a significant bottleneck. Converting the inner array to a $O(N + M)$ time complexity.
src/routes/api/proposals/voters/add/+server.tsandsrc/routes/api/proposals/voters/remove/+server.tsby converting the inner array to aSetbefore filtering.🎯 Why: The original code used
.includes()inside a.filter()loop, resulting in anSetfirst reduces this to📊 Impact: Expected to reduce processing time significantly for large lists of owners and voters. Based on a standalone script, this reduces execution time from ~1.1s down to ~17ms for lists of 50000 and 10000 items.
🔬 Measurement: Verified functionality by running tests (
pnpm test:unit --run), format (pnpm run format), type-checking (pnpm run check), and linting (ESLINT_USE_FLAT_CONFIG=false pnpm lint). Tests passed successfully.PR created automatically by Jules for task 13226242221942608273 started by @yeboster
