Summary
A systematic approach to finding and fixing performance bottlenecks without guessing. You get a clear four-step workflow (baseline, identify, fix, validate), concrete Core Web Vitals targets, and tool recommendations mapped to specific problems. The included Lighthouse audit script handles automated profiling, while lookup tables help you interpret DevTools output and prioritize fixes. What I like here is the anti-patterns section that pushes back on premature optimization and reminds you to profile before you optimize. Best used when you're staring at slow page loads or janky interactions and need a methodical way to diagnose what's actually wrong rather than throwing random performance tricks at the wall.
