Does lazy loading always work well? What problems can there be with chunks?

Lazy loading improves performance by loading resources as needed, but it doesn't always work perfectly.

Problems with chunks in lazy loading:

• Network overload: if there are too many chunks, the browser may make many requests, slowing down the loading.
• Dependency management: improper code splitting can lead to duplication or loading unnecessary modules.
• User experience: on slow internet or weak devices, chunk loading can cause delays and interface flickering.

It's important to balance the size and number of chunks, use preloading for critical parts, and optimize the lazy loading strategy.
