AbortController is how fetch learned to clean up after itself

Short summary

AbortController solves a common React pitfall: when a component unmounts or dependencies change before a fetch completes, stale responses can overwrite newer data or cause memory leaks. Pass the controller's signal to fetch and abort it in useEffect cleanup; handle the resulting AbortError to avoid console noise. Extract this pattern into a reusable useAbortableFetch hook to reduce boilerplate.

• •AbortController cancels fetch requests when components unmount or dependencies change
• •Aborting fetch rejects the promise—catch AbortError specifically to avoid console errors
• •Extract the pattern into a useAbortableFetch hook to reduce repetitive lifecycle code
