Memory Leaks

Memory leaks usually happen when unused resources (e.g., DOM elements, event listeners, or data structures) are not properly released, causing unnecessary memory consumption.

Common Solutions:

1. Clean up event listeners: Remove listeners when components unmount:

useEffect(() => {
  window.addEventListener('resize', handler);
  return () => window.removeEventListener('resize', handler);
}, []);

2. Abort fetch requests: Use AbortController to cancel pending API calls:

const controller = new AbortController();
fetch(url, { signal: controller.signal });
return () => controller.abort();

3. Avoid stale references: Ensure state updates do not persist after unmounting by checking component state.

4. Use profiling tools: Monitor and analyze memory usage using browser DevTools to detect leaks.
