…ering Extracted repeated `.filter().length` array traversals out of JSX mapping operations in ProjectsModule and MaintenanceModule. Calculated both filtered lists and specific aggregated status counts simultaneously in a single useMemo hook in each component, preventing redundant O(N) loops on every re-render.

💡 What:
Replaced direct
.filter().lengtharray traversal calls inside the JSX loops ofProjectsModule.jsxandMaintenanceModule.jsxwith single-passuseMemoblocks. These blocks now calculate the necessary sub-array and aggregate the status counts simultaneously in one O(N) loop.🎯 Why:
Previously, iterating over tabs or priority elements repeatedly filtered the large
projectsandtasksarrays directly inside the render cycle (e.g.,projects.filter(p => p.status === v).length). This resulted in multiple expensive, redundant loops on every single re-render or typing interaction in the search bar.📊 Impact:
Reduces the time complexity per re-render in these components from O(N * M) (where N is data length and M is tabs/filters) down to O(N). Significantly improves overall responsiveness, especially when typing in the search bar or viewing large data sets, by eliminating dozens of redundant array traversals.
🔬 Measurement:
Load up the application and observe rendering speed when rapidly switching tabs or filtering lists via text in the Maintenance and Projects pages. Check the React Developer Tools profiler to verify reduced component rendering times for those modules.
