2 things to look at
- no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
- 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

CPU Profiling
Table of Contents
Overview
CPU profiling identifies which functions consume most CPU time, enabling targeted optimization of expensive code paths.
When to Use
- High CPU usage
- Slow execution
- Performance regression
- Before optimization
- Production monitoring
Quick Start
Minimal working example:
Browser Profiling:
Chrome DevTools:
Steps:
1. DevTools → Performance
2. Click record
3. Perform action
4. Stop recording
5. Analyze flame chart
Metrics:
- Function call duration
- Call frequency
- Total time vs self time
Firefox Profiler:
- Built-in performance profiler
- Flame graphs
- Timeline view
- Export and share
React Profiler:
- DevTools → Profiler
- Component render times
- Phase: render vs commit
- Why component re-rendered

Best Practices
✅ DO
- Follow established patterns and conventions
- Write clean, maintainable code
- Add appropriate documentation
- Test thoroughly before deploying
❌ DON'T
- Skip testing or validation
- Ignore error handling
- Hard-code configuration values
