Hey guys,
Welcome to another edition of Import React by Cosden Solutions!
In this week’s issue: we’re diving into advanced React state patterns, why some companies are rethinking React, and a code review that genuinely surprised me. Plus, a look at TypeScript’s rise to #1 and how AI is reshaping developer careers.
Let's get into the newsletter! 🤙
Sevalla: Deploy Anything Without Limits or Tricks
If you’re searching for a platform that…
✅ lets your whole team collaborate with no seat limits
✅ scales apps globally on Kubernetes across 25 regions
✅ serves static sites fast on Cloudflare’s 260+ edge network
✅ includes managed databases & object storage under one roof
✅ charges only for what you use (no hidden fees, no surprises)
…then todays sponsor, Sevalla is worth a serious look.
It combines the best of Render, Railway, Fly.io, and Vercel—without the artificial restrictions or “gotchas” that slow teams down. Think Heroku’s developer experience, re-imagined for 2025.
And because it’s backed by Kinsta, you also get real human support and enterprise-grade security (SOC II Type 2, ISO 27001, GDPR compliance) baked in from day one.
⚡️ The Latest In React
🫂 Encapsulate as much state as possible in your component
TL;DR, Encapsulate your state. Don’t make the parent micromanage every tiny change. In this post, Black Sheep Code argues that components like buttons and autocompletes should handle their own transitions, from loading to success to error, instead of passing state down as props. By letting the component manage its async flow internally, your tests become cleaner, your interfaces simpler, and your code far more reusable. Think of it this way, the parent shouldn’t care how the button loads, only what happens when it’s done.
🤔 Why companies choose React (and when you shouldn't)
React dominates 2025 startup funding with $2.52B (88.6%), but 85% of projects across all frameworks are abandoned. Smaller tools like Svelte and Vue boast higher survival and satisfaction rates, showing that popularity doesn’t equal longevity. React wins for hiring ease, but if you value developer happiness and cleaner codebases, Vue or Svelte might be the wiser bet.
📽 React Code Review That Surprised Me!
In this video, we’re checking out a React project that genuinely surprised me, built by a dev just beyond the junior stage. The code patterns are solid and full of potential, only needing a bit more polish and experience to refine. Overall, it’s a strong foundation for building clean, scalable React apps.
🧠 AI leads TypeScript to #1
TypeScript officially became GitHub’s #1 language in 2025, surpassing Python and JavaScript after growing 66% year over year. Its rise reflects how developers are embracing typed systems for AI-assisted coding, where stricter types help catch LLM-generated errors early. The full Octoverse report also dives into AI growth, global developer trends, and security automation, but this milestone marks a generational shift in how modern code gets written.
🔎 Your URL Is Your State
This piece explores how URLs can act as powerful state containers, not just web addresses. By encoding app state directly into the URL, developers unlock shareability, bookmarking, and resilience without extra libraries or storage. The author shows how thoughtful URL design can replace complex state tools. and why good URLs are both UI and data contracts.
Introducing Cosden Code
It’s a quiet week in React, so I thought it would be a good time to introduce you to something special I’ve been building.
I built Cosden Code because I was tired of the same broken system, scattered YouTube tutorials, half-finished Udemy courses, and no help when you're stuck at midnight with a bug.
This is different. You get a complete curriculum from beginner to advanced, covering JavaScript fundamentals, hooks, state management, design patterns, and real projects. Every lesson includes a thorough video explanation, hands-on coding in a built-in IDE (no setup required), and even an AI mentor trained on the exact concept you're learning.
And here’s the best part, this platform evolves with you. New courses and modules are added every month. When React drops new features, you get them. When best practices change, your access updates automatically.
One platform. One clear roadmap. Access to everything. You’ll never need to course hop again.

🧠 AI & General Programming
👀 Web elements know about the user, device, variables, layout and more
CSS named container queries are changing how components think. Instead of relying on scattered global styles, elements can now “know” where they live, whether they’re in a sidebar, footer, or callout, and adapt automatically. Combined with user prefs, device traits, and layout context, components are becoming self-aware, owning their presentation across any scenario.
🤖 What's up with Anthropic predicting AGI by early 2027?
Anthropic predicts AGI by early 2027, expecting systems as capable as “a country of geniuses in a datacenter.” But researcher Ryan Greenblatt argues the odds are only ~6%, saying such progress would demand unrealistically fast leaps in automation and research speed. Trend data suggests powerful AI is more likely within 5–10 years, not two, and that society is still woefully underprepared for when it does arrive.
💰TikTok migrates critical Go APIs to Rust for 2x performance and $300K savings
TikTok rewrote its most critical Go APIs in Rust, achieving 2x performance and saving $300K per year. At 100K QPS, Go’s garbage collection and serialization overheads caused CPU bottlenecks, so the team migrated only the CPU-bound APIs. The results were dramatic, 33% lower CPU use, 72% less memory, and 76% lower p99 latency, showing the power of targeted Rust adoption over full rewrites.
🤫 The Silent Career Killer Most Engineers Miss
Silent disagreements are one of the biggest hidden blockers in engineering careers. They erode trust, delay projects, and stall promotions, because silence isn’t alignment. Hemant Pandey explains that strong engineers don’t just write code, they drive clarity and alignment. The key is to follow up, ask the hard questions, and reward honesty over harmony.
💼 AI Is Making It Harder for Junior Developers to Get Hired
AI isn’t just changing how we work, it’s changing who gets to work. A Harvard study shows that companies adopting generative AI cut junior roles by nearly 10% within six quarters, while senior hiring stays stable. Entry-level jobs are vanishing, not from layoffs but from silence. Without juniors, there’s no future talent pipeline, just short-term efficiency and long-term decay.
