SSG vs SSR in Next.js 15!
Next.js 15 makes server-side rendering the default, treating all components as Server Components unless specified otherwise with 'use client' for Client Components. SSG (Static Site Generation) provides high speed, security, and SEO benefits for static content, while SSR (Server-Side Rendering) offers dynamic content and personalization advantages. The choice between SSG and SSR depends on whether the site content is static or frequently updated.
