- Better User Experience through Reactive Interfaces
- Strong Community and Extensive Resources
✖Limitations
- Steep Learning Curve for Beginners
- Excessive Flexibility Can Lead to Inconsistencies
- Dependency on External Libraries for Full Functionality
Trade-offs
Metrics
- Application Load Time
Time taken to fully load the application.
- User Interactions per Session
Number of interactions a user has during a session.
- Error Rate
Number of errors occurring during usage.
