Replaced an O(N) loop that queried and attached event listeners to individual project buttons during every render cycle. By using event delegation on the parent container, we eliminate redundant DOM querying and reduce garbage collection overhead, especially when filtering the project list.

💡 What: Replaced the O(N)
querySelectorAlland individualaddEventListenerloop insideProjectManager.renderProjectswith a single O(1) delegated event listener attached to the parent.projectsGridcontainer in the initialization phase.🎯 Why: When the user filtered projects, the application was destroying the DOM elements using
innerHTML, rendering new ones, querying the DOM for all newly created.view-project-btnelements, and attaching individual event listeners. This created significant memory bloat, unnecessary DOM queries, and garbage collection overhead on every filter action.📊 Impact: Eliminates O(N) DOM querying per render. Reduces memory allocations and garbage collection pauses, leading to smoother 60fps rendering during rapid UI filtering, especially on lower-end devices.
🔬 Measurement: Repeatedly click filter buttons rapidly. The Javascript execution time and garbage collection pauses measured in the Chrome DevTools Performance tab will be noticeably reduced.
