What is React?
A JavaScript library for building user interfaces, developed by Meta (Facebook), widely used for web development.
Definition
React is an open-source JavaScript library developed by Meta (Facebook) for building user interfaces, particularly single-page applications (SPAs). React uses a component-based architecture — UIs are built from independent, reusable pieces called components. React's virtual DOM enables efficient updates, re-rendering only what changes instead of the entire page. React is the most widely used frontend JavaScript library, with a massive ecosystem including Next.js (full-stack), Remix, and TanStack Start (SSR-capable).
Why It Matters for Indian Businesses
React is the industry standard for web application development, used by Facebook, Instagram, Airbnb, Netflix, and thousands of Indian tech companies. Building with React means access to the largest pool of frontend developers in India, the richest ecosystem of libraries and tools, and a framework that scales from MVPs to enterprise applications without changing the fundamental architecture.
Real-World Example
A fintech startup in Bangalore builds their loan application portal with React (frontend) + Node.js (backend). The React component architecture means their UI team can build individual components (loan calculator, eligibility checker, document upload, EMI selector) independently and assemble them into the complete application. When they add a new product type, they reuse 70% of existing components, reducing development time by 3 months.
