- Consolidated multiple `.map().filter()` and `.flatMap()` calls in `src/hooks/use-platform-stats.ts` into a single loop. - Consolidated ~8 redundant iterations over the `profiles` array in `src/pages/about-page.tsx` into a single `for` loop. - Replaced secondary iterations over the arrays to calculate totals with size lookups on the generated sets/dictionaries. - Added a Bolt learning journal entry in `.jules/bolt.md`.

Excellente initiative de Pull Request ! Cette PR s'attaque à un problème de performance courant et démontre une bonne compréhension des optimisations en JavaScript, en particulier dans un contexte d'application web dynamique comme BisoMapTech. Le fichier Voici la revue détaillée : Analyse Détaillée de la Pull Request1. Failles de sécuritéAucune faille de sécurité majeure n'est introduite ou exposée par cette Pull Request. Les modifications concernent uniquement la logique de traitement et d'agrégation de données existantes, sans interagir avec des entrées utilisateur non validées ou des systèmes sensibles (authentification, base de données directe).
🟢 Faible - Aucun problème de sécurité détecté. C'est une refonte interne qui n'impacte pas la surface d'attaque. 2. Bugs potentielsLes changements apportés semblent robustes et gèrent correctement les cas limites.

💡 What: Refactored the
computeStatslogic in bothsrc/pages/about-page.tsxandsrc/hooks/use-platform-stats.tsto perform data aggregation in a singleO(n)pass instead of chaining multiple array methods.🎯 Why: When rendering the About page or loading platform stats, the codebase was previously doing 8-10 consecutive iterations over the entire
profilesarray using.map().filter(),.flatMap(), etc. This blocked the main thread and caused excessive intermediate array memory allocations.📊 Impact: Reduces time complexity from
~8 * O(n)to1 * O(n)for profile parsing. Eliminates intermediate array allocations, reducing memory usage and garbage collection pauses on lower-end devices.🔬 Measurement: Verify by running
pnpm test(all pass) and manually profiling the execution time of thecomputeStatsfunction in Chrome DevTools when loading the/a-proposroute with thousands of mock profiles; execution time should be significantly shorter without long GC tasks.PR created automatically by Jules for task 11162564375199497311 started by @KxlSys
