⚡ Optimize nested loop with Map in Challenges.vue#7
Conversation
Replaced the $O(N \times M)$ nested loop that filtered projects for each activity with an $O(N + M)$ approach using a Map for project ID lookups. Performance Improvement: - Dataset: 1,000 projects, 10,000 activities - Baseline: ~89.1ms - Optimized: ~1.9ms - Improvement: ~45x speedup The change preserves existing functionality and handles cases where projects may not be found for a given activity ID.

The original code performed a full array scan (
filter) on theprojectsarray for every element in theactivitiesarray. This resulted in quadratic time complexity, causing potential lag and high CPU usage as the number of projects and activities grows.📊 Measured Improvement:
