Why lazy-load movie posters in React?
Because a browse page can have hundreds of posters. Loading them all at once slows the initial render significantly. Lazy-loading means images load as they enter the viewport, keeping the page fast.

More FAQs in Fetching and Caching Movie Data in a React Netflix Clone
Cache responses so you do not re-fetch the same data, use React Query for server state, fetch only what each view needs (list data for carousels, full details only for the modal), parallelize independent requests with Promise.all, and lazy-load images.
Because a Netflix clone fetches a lot of data, and React Query handles caching, invalidation, refetching, and loading state for you. It removes most hand-written fetching logic and keeps the app fast and consistent.
No. Fetch list data for carousels (poster and title), and full details only when the user opens the detail modal. Fetching full details up front wastes bandwidth and slows the initial load.
