Frequently asked questions

What does a React developer do?

A React developer builds interactive user interfaces for web applications using React and JavaScript. They build components, manage state with hooks, connect to APIs and fix UI bugs. At the entry level they deliver assigned features, write component tests and learn the React ecosystem with support from senior engineers, matching designs closely as they go.

Is React in demand in India?

Yes, strongly. React is the most widely used frontend library in India, powering web applications across startups, product companies and service firms. Its component model and large ecosystem make it a safe skill to learn. Freshers who know React, JavaScript and hooks, and build a couple of projects, find frontend and full stack openings readily.

Is React a framework or a library?

React is a library focused on building user interfaces, not a full framework. It handles the view layer, and you add tools around it for routing, state management and data fetching as needed. This gives flexibility but also choices to make. Frameworks like Next.js build on React to add structure for larger applications.
