Lazy loading là gì và cách implement trong React?

February 15, 2026

Quick summary

Lazy loading is a performance optimization technique that defers the loading of non-critical resources (images, components, routes) until they are needed, reducing the initial bundle size. In React, this is primarily implemented using `React.lazy()` with `<Suspense>`, dynamic imports, or the native `loading="lazy"` attribute for images.
