React.js, a JavaScript library, focuses on building user interfaces and requires extra libraries for functionalities like routing and data fetching. Next.js, a framework built upon React, streamlines development by offering these features pre-built. Ideal for SEO and e-commerce, Next.js prioritizes speed and ease of use, while React's flexibility caters to complex web apps. Though React boasts a larger community and easier learning curve, Next.js offers faster development for those familiar with React.
