  3. React is declarative and efficient
  4. Provide easy code maintainability and reusable code with the usage of components feature.
  5. React provides faster application execution with the use of Virtual DOM approach
  6. Provide easy debugging as code is developed using java script.
  7. React provides statefull components with the usage of state and props

Disadvantages of ReactJS

  • Frequent changes in the ReactJS library makes it difficult for developers to keep upgrading with the features and makes it a on -going learning experience.
  • ReactJS covers the “View” part as part of the MVC Architecture and thus need to integrate with other frameworks for application development.
  • JSX being an extension to java script provides the conversion of html tags to react elements and this somehow makes it difficult for developers to understand the react functionality.
