React.js allows for reusability of code component during the designing the user interfaces, thus it save times and prevents the repetition of the same task. React.js components are isolated or separated, hence they are open to easy updates and the change does not affect the development process.
For a simple, fast and scalable web design, developers can choose this framework over Angular.js.
Node.js comes with a huge number of free tools and enables the reusability and sharing of code components. It is ideal to build fast and high-performance backend applications.
