How do React Router v6.4 loaders change data fetching from useEffect?
This tests moving from fetch-on-render to render-as-you-fetch. Explain that loaders fire before render, removing useEffect waterfalls, while the router ignores stale promises on interruption. Red flag: calling loaders just useEffect outside the component.
This tests whether you understand React Router's move from fetch-on-render to render-as-you-fetch. A strong answer says loaders fire before the component mounts, removing useEffect waterfalls and manual cleanup. It also notes the router auto-handles race conditions by ignoring stale loader promises when navigation interrupts them, so AbortControllers are unnecessary for basic cases. Red flag: calling loaders just useEffect outside the component.
