How does caching work in Next.js?

Next.js provides multiple caching strategies for improving performance. Data requests, rendered pages, and static assets can be cached depending on configuration. Developers can control caching behavior using fetch options, revalidation settings, and route configurations. Proper caching reduces server load and improves response times.
