React.js, on the other hand, is a library for building user interfaces using a component-based architecture. React uses a virtual DOM, which allows it to optimize updates to the real DOM and improve the performance of web apps. React also encourages the use of functional components, which can make the codebase more predictable and easier to reason about.
One of the main benefits of React is its performance, due to the use of a virtual DOM, which can help optimize updates to the real DOM, making web apps built with React faster and more responsive. Additionally, the component-based architecture of React, makes it easy to build reusable and modular code, which can help to improve maintainability and scalability of the web app.
React also have a big community and a wide range of tools and libraries, it is a battle-tested library and is widely used in production for building web applications, it has a strong ecosystem that continues to evolve.
However, React can have a steeper learning curve than Vue, especially for developers who are new to the concept of a virtual DOM and functional components. React also encourages a more complex file structure, which can make it harder for developers to navigate the codebase.
