Performance Notes
Simple sketches run efficiently in browsers
Complex sketches with many objects may lag
Avoid excessive DOM manipulations in `draw()`
Use `frameRate()` to control loop speed
Consider optimization for real-time animations
Security Notes
Runs in browser sandbox, so minimal security risk
Be cautious when loading external assets
Avoid injecting untrusted scripts
Use HTTPS for secure asset loading
Monitor memory usage for heavy multimedia sketches
Monitoring Analytics
Use browser console for debugging
Monitor FPS and performance in complex sketches
Log user interactions for analysis
Test across devices and browsers
Document behavior for iterative improvements
Code Quality
Organize sketches with functions and classes
Minimize global variables where possible
Comment code for clarity
Test sketches incrementally
Optimize animation loops for performance
