React | JavaScript | Redux | GraphQL
React is a JavaScript library for creating user interfaces. It is widely used for building single-page applications and mobile apps because it allows efficient rendering of components and a declarative structure for building user interfaces.

React was developed by Facebook and is maintained by Facebook and a community of developers. It is declarative in nature, meaning developers can specify how the user interface should look, rather than how it should be implemented. This makes it easier to create and maintain complex user interfaces because the code is more predictable and easier to understand.

React breaks down a user interface into small, reusable components that can be easily assembled into a complete interface. These components can be thought of as “building blocks” that can be easily reused and adapted to create a variety of different surfaces.

React is often used in combination with other technologies such as Redux or GraphQL to manage state and data in a web application. It can also be used with various libraries and frameworks like React Router and Next.js to handle routing and server-side rendering.

Overall, React is a popular choice for creating dynamic, interactive user interfaces and is widely used in modern web development.

BITS experts have used React in a variety of projects. A selection of case studies and references can be found below.
