Why Use React JS Instead of JavaScript?

  • ReactJS is actually a JavaScript library, so it's not a question of using React instead of JavaScript. Rather, React is a library that is built with JavaScript and provides developers with a powerful toolset for building complex user interfaces.
Here are some reasons why developers might choose to use ReactJS over plain JavaScript:
  • Component-Based Architecture: React's component-based architecture makes it easier to build complex user interfaces by breaking them down into smaller, reusable components. This allows developers to build UIs more quickly and with fewer errors.
  • Virtual DOM: React's use of a Virtual DOM makes it possible to update the UI more efficiently and with less overhead, resulting in better performance and faster rendering times.
  • Data Flow: React's unidirectional data flow makes it easier to manage state and data flow in an application, resulting in more predictable and easier-to-debug code.
  • Large and Active Community: React has a large and active community of developers who contribute to the library, share knowledge and resources, and help to resolve issues.
  • React Native: React can also be used to build native mobile applications through React Native. This allows developers to use the same codebase to build applications for both web and mobile platforms, reducing development time and cost.
  • Toolset: React comes with a comprehensive set of tools and libraries for building complex user interfaces. This includes tools for testing, debugging, and styling, making it easier to develop and maintain large-scale applications.
  • Overall, ReactJS provides developers with a powerful toolset for building complex user interfaces more quickly and with fewer errors. Its component-based architecture, virtual DOM, and unidirectional data flow make it easier to manage state and data flow in an application, resulting in more predictable and easier-to-debug code. Its large and active community and comprehensive toolset also make it a popular choice among developers.
