This guide covers diagnosing INP using the web-vitals attribution build and Chrome DevTools, then fixing it through four main strategies: breaking long tasks with scheduler.yield() (with a setTimeout fallback), optimizing event handlers by deferring non-visual work via requestIdleCallback or Web Workers, eliminating layout thrashing by batching DOM reads and writes, and controlling third-party scripts with facades and dynamic imports. Includes working code examples for each technique and a 10-step optimization checklist. ## Full article daily.dev links to this article rather than hosting it.
