⚡ Bolt: Optimize schedule filtering with Set lookup#191
Conversation
💡 What: Converted the `savedSessionIds` array into a `Set` before filtering the schedule. 🎯 Why: `Array.includes()` inside a `.filter()` iteration runs in O(N * M) time complexity. `Set.has()` reduces this to O(N + M). 📊 Impact: Reduces computational overhead significantly on re-renders when users have a large schedule and toggle between views. 🔬 Measurement: Run the performance tests (e.g. `npm run test __tests__/components/schedule/ScheduleGrid.perf.test.tsx`) and observe UI frame-drops when toggling 'My Schedule'.

Code Review
This pull request optimizes the session filtering logic in ScheduleContainer.tsx by converting the savedSessionIds array into a Set, which improves the time complexity from O(N*M) to O(N+M). Additionally, it updates the .jules/bolt.md documentation to record this performance optimization. Feedback was provided regarding the documentation update, specifically pointing out duplicated entries and a typo in the first entry, with a suggestion to consolidate the information.

| **Learning:** Found an O(N*M) performance bottleneck in `ScheduleContainer.tsx` where `Array.includes()` was being called inside a function on every re-render or schedule update. | ||

The entries for 'Array filtering with repeated includes()' are duplicated. The first entry (lines 20-22) also contains a typo where the function name is missing ('inside a function'). It is recommended to remove the redundancy and keep the more accurate entry.

Remove the duplicate entry and fix the truncated description.
Lines 20–22 and 23–25 are two near-identical sections with the same title. The 2026-05-03 entry (line 21) has an incomplete Learning string — the word .filter() was dropped, leaving a double space and a dangling "a function". The 2026-03-24 entry has the correct wording but an inconsistent/older date. The two should be collapsed into one correctly dated and worded entry.

💡 What: Converted the
savedSessionIdsarray into aSetbefore filtering the schedule incomponents/schedule/ScheduleContainer.tsx.🎯 Why:
Array.includes()inside a.filter()iteration runs in O(N * M) time complexity, leading to redundant linear scans.Set.has()reduces this lookup to O(1), lowering total time complexity to O(N + M).📊 Impact: Reduces computational overhead on re-renders when users with a large number of saved sessions toggle the filter or switch tabs.
🔬 Measurement: Run the existing component performance tests via
npm run test __tests__/components/schedule/ScheduleGrid.perf.test.tsxand observe rendering metrics.PR created automatically by Jules for task 1695331495068705416 started by @anyulled
