In the world of a diverse group of frameworks, one of the popular frameworks for ‘hitting the ground running’ is Next.js. Did you know that mobile devices account for 2/3 of all web usage? Given this, it is crucial to optimize websites and develop web applications for the best possible mobile experience. Due to this, developing high-performance web applications and lightning-fast static web pages requires robust technology.
