• Third-party integration is difficult;
• Migration issues common when switching to the latest version;

Pros and Cons of ReactJS

• Allows using 3rd party library integration;
• Migrating between versions easy;


• ReactJS is not a full-scale framework;
• Integration calls for complex configuration and setup;
• Developers need an in-depth knowledge to integrate user interface into an MVC framework;
• Developers with object-oriented programming may find it difficult to use as it moves away from class-based components;
• Lack of official documentation is a deficiency;
