Why Optimize Performance?
- Improve loading speed
- Enhance user experience
- Reduce resource usage
- Handle large applications efficiently

Efficient Rendering
- Use v-if instead of v-show when needed
- Use key in v-for loops
- Avoid unnecessary re-renders
Code Splitting
Split your application into smaller chunks to load only required parts.
Computed vs Watch
| Feature | Computed | Watch |
|---|---|---|
| Usage | Derived data | Side effects |
| Performance | Cached | Runs every change |
Best Practices
- Use lazy loading for routes
- Minimize component size
- Use computed properties
- Optimize API calls
Common Mistakes
- Overusing watchers
- Large components
- Ignoring key in loops
- Not using lazy loading
Conclusion
Optimizing Vue performance ensures fast, responsive, and scalable applications. Following best practices improves both speed and user experience.
