What is ReactJS?
React’s main advantage lies in its ability to efficiently update and render components when data changes, using what’s called the Virtual DOM. Instead of fully refreshing the page or reloading components, React compares the current UI with the new one and smartly updates only the changed parts, resulting in a smoother and faster user experience.
Another defining feature of React is its component-based architecture. This means that the UI is broken down into individual, reusable pieces (components), which can manage their own state and render logic. This modularity not only promotes code reusability but also makes the codebase easier to maintain.
React also seamlessly integrates with various back-end technologies, making it versatile and an excellent choice for both new and existing projects. With its supportive community, rich ecosystem, and backing by a tech giant like Facebook, React has established itself as a go-to library for web development.
In recent years, with the introduction of React Native, the power of React has extended beyond web applications, enabling developers to build mobile applications with a similar component-based structure.
