What is React?
React is a JavaScript library for building user interfaces with reusable, component-based architecture. Developed by Meta, it's the most popular frontend framework and powers millions of web applications.
React interviews focus on components, hooks, state management, rendering, and performance optimization. You'll discuss the virtual DOM, lifecycle methods, and how to build scalable, maintainable UIs.
React expertise is essential for modern frontend development. Master the library and you'll be competitive for frontend and full-stack roles at top companies.
