Why React is trusted for modern web applications
React is the most widely used front-end library for building modern web applications. Its component-based approach makes complex interfaces faster to build, easier to test and simpler to maintain as your product grows, and it is backed by a huge global developer community.
With Next.js, React sites are also fast and SEO-friendly, making React ideal for SaaS products, dashboards and marketplaces. It pairs well with Laravel backends.
