What is the senior dev approach to data fetching in React?

Ditch raw useEffect; adopt TanStack Query, SWR, or RTK Query for caching, deduping, and error handling out-of-the-box.

Why is useEffect bad for data fetching in React?

It ignores real-world edge cases like races, caching, and retries—leading to bugs in production.

Does TanStack Query replace useEffect entirely?

Mostly yes for data; useEffect still shines for DOM effects, subscriptions, or non-data side effects.
