Matteo Collina drops the mic with actual numbers: noop functions are 5-8x faster than optional chaining, which explains why Fastify isn't just being stubborn about it. Next.js 16 arrives with Turbopack finally stable, React Compiler support, and everyone pretending they knew it was coming all along. Meanwhile, someone finally said what we're all thinking: why are we downloading 500MB Electron apps when cURL has been sitting on our machines since forever?
Also in this issue: Nadia Makarevich delivers the data-driven RSC vs SSR vs CSR performance comparison we've been waiting for, Anton Zaides challenges the sacred cow of mandatory code reviews with data from 400+ companies (spoiler: quality beats quantity), and lighthouseapp.io wrote the comprehensive RSS reader comparison covering everything from on-device to self-hosted solutions.
Steve Klabnik is betting on jj—version control that works with Git repos minus the Git headaches—and Vercel's Workflow Development Kit promises functions that pause for months and survive crashes without the infrastructure complexity. Jovi Decroock finally explains why signals are different (render where you use, not where you create), and Phil Schmid dives deep into Agent 2.0 architecture with explicit planning, hierarchical delegation, and persistent memory patterns.
Enjoy!
