## Source excerpt

I've published a few articles on Medium that may interest the reader here: requestAnimationFrame Scheduling For Nerds Understand how rAF callbacks are scheduled and why its very reasonable to have multiple callbacks execute within the same frame. Debugging Node.js with Chrome DevTools The canonical guide to using the Chrome DevTools UI for debugging Node.js. It definitely beats console.log. ;) Aside from that, I've been busy working on Lighthouse, performance metrics, tooling, and DevTools.
