😵 Is This Tech Dead?

Hey there.

Welcome to Full Stack Focus.

Here’s everything you need to know this week in the world of full-stack development.

Programming

😵 Is This Tech Dead?
Ever wonder if your favorite programming language is basically a ghost? Meet the "Deaditude Score", a brutally honest (and hilarious) tracker that measures how close a tech is to the grave, blending 7 signals like GitHub activity, StackOverflow buzz, and even YouTube tutorials. Search, sort, and cry as you browse ~50 technologies.

🛠️ How JavaScript Works Behind the Scenes
Ever wonder how JavaScript juggles a million things with just one hand? It’s all thanks to the Call Stack, Web APIs, the Task Queue vs. Microtask Queue showdown, and the all-powerful Event Loop. JavaScript doesn’t compile like C or Go, it interprets on the fly, somehow keeping everything from crashing while you scroll memes and sip coffee. This article breaks it all down in a clear and concise manner.

🤖 Deploying agents as real-time APIs 101
Ever wanted to make game characters that feel real? In Lesson 4 of the open-source PhiloAgents course, you'll learn how to build smart AI agents that don't just think, but actually talk and react in real time. They show you how to connect your agents to the web using APIs and WebSockets, so they can become part of live games and apps.

AI won't take over coding. Developers who know how to leverage AI will.

Here's how to level up your dev skills with AI:

• Sign up for AI by Devs. The AI newsletter built by developers, for developers.

• Master AI coding tools, technical tutorials, and industry news in just 3 minutes a day.

• Become 10X more productive by integrating AI into your development workflow.

Front-End

💪 Impossible Components
Dan Abramov is back with another post, this time he’s tackling the weird world of “impossible” React components, the ones that try to mix server-side magic (like reading files) with client-side interactivity (like handling clicks). Traditional React can’t pull it off, but React Server Components are here to bridge that messy gap. Dan even drops a live example you can tinker with yourself.

🆕 New React Features Announced
Big news from the React team: two new experimental features just dropped, View Transitions and Activity! View Transitions make it insanely easy to add slick animations to your app, while Activity lets you hide and show parts of the UI without breaking a sweat. These features are stable enough to test today in react@experimental, with even more cool stuff like Performance Tracks and Compiler IDE Extensions on the way.

👀 Full-Stack React.js Chat with AI SDK
In Part 1, Robin showed how to build a basic AI chat interface. Now in Part 2, it’s time to level up: ditch those raw OpenAI API calls and swap them out for Vercel’s slick AI SDK.
