🕰️ It’s About Time! Time Zones in TypeScript at iJS London Working with dates and time zones can get tricky fast — especially when your server, your users, and the location they care about are all in different time zones. Thank you to Michael Dowden for showing how to make sense of it all in his iJS London session “It’s About Time! Practical Examples of Time Zones in TypeScript.” 🌍 From travel and scheduling to parking and logistics, Michael shared real-world examples of how software can represent time more reliably. 🧩 The session covered practical TypeScript approaches, the JavaScript Date object, Luxon, normalized data, and a look at Temporal — with this video offering a glimpse into the insights shared on site. 🔎 Explore the program and see what else is happening at iJS London: f.mtr.cool/rakfegunvw #iJS #JavaScript #TypeScript #TimeZones #Luxon #Temporal #ReactJS #Angular #NextJS #WebDevelopment #SoftwareDevelopment

📹 Were you in the session? No? Then here’s a quick glimpse into Younes Jaaidi’s talk “Charted Coding: Beyond AI-Assisted TDD” at iJS London. In this session, Younes showed how to bring more structure into AI-assisted development — moving beyond messy code-and-fix loops toward predictable, maintainable workflows teams can actually trust. 🧠 From lightweight design docs and scaffolding to test-guided AI workflows, the session explored how Charted Coding helps keep AI from vibe-coding your project into chaos. ⚡ Attendees also got insights into MCP servers, WallabyJS, and practical ways to make AI-assisted TDD smoother and more reliable. Missed it? There’s still more to discover at iJS London. 🗓️ Explore the program and see what’s coming up next: f.mtr.cool/kwgnwysaic #iJS #JavaScript #AI #GenerativeAI #TDD #Testing #ReactJS #Angular #NextJS #DeveloperTools #SoftwareDevelopment

🧩 Inside iJS London: Scaling Next.js in Kubernetes Without the Pain Couldn’t catch @matteocollina’s session live? This video gives you an exclusive glimpse into his talk on scaling Next.js in Kubernetes. ⚙️ Matteo broke down why familiar Node.js scaling setups like PM2 clusters and single-CPU pods can struggle when React SSR workloads get CPU-heavy — and why that often leads to idle infrastructure, overloaded pods, and rising error rates. 📊 He also showed how Watt and SO_REUSEPORT bring load distribution closer to the Linux kernel, helping teams improve latency, reliability, and coordination overhead in real-world deployments. Missed this one? There’s still plenty more to discover at iJS London today. 🔎 Explore the program and see what’s coming up next: f.mtr.cool/ulyucznesm #iJS #JavaScript #NextJS #Kubernetes #NodeJS #ReactJS #WebPerformance #SoftwareArchitecture
