React is a modern web development framework that uses a declarative paradigm to create reusable components. These components are akin to Lego bricks that are individually responsible for a particular state, and when assembled together, they form an entire user interface. React has many libraries available, such as Create React App.
In React, the state of a component is used to track changes to data over time. This allows you to create interactive web applications. Managing state in class-based components is an essential skill. A component can receive props (properties) passed to it by its parent. Props specify the state of a component and its initial value.
ReactJS is an excellent choice for developers who need to create a fast and responsive UI. It can handle complex UI interactions and communicate with the server in record time. It is easy to learn and can help you build modern, fast-performing applications. It requires only minimal knowledge of HTML and JavaScript.
In addition to its popularity with web developers, React has found use in the mobile environment. It’s used in the Uber Eats app to connect drivers and restaurants. The developers of the Uber Eats application faced difficulties converting restaurant dashboards from the web to mobile, and that is where React Native came in. With React Native, Uber Eats has been able to scale and grow.
