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.
