My React tip on discriminated unions reached 114,000 developers. The 68 comments found four places where I was wrong, including a four line example that breaks the guarantee I was selling.
Microsoft just shipped the TypeScript 7.0 RC. Compiler rewritten in Go. 10x faster builds. But the part nobody's talking about is what breaks in migration and what it means for your next technical interview.
A developer messaged me on Tuesday morning asking why his deploy was broken. He had just upgraded a small internal tool to Node.js 26 the same day the release dropped. Local tests passed. CI passed. The container built. Then the service refused to start in production with an error nobody on his team had ever seen before.
I run jsgurujobs.com. The site has 430+ JavaScript job listings, 115+ blog posts, a newsletter with 4,200 subscribers, and a Telegram channel.
A company posted a senior React position on my board four months ago. I noticed it because the listing stayed active longer than anything else on the platform. Most postings get taken down after 30 to 60 days,
Atlassian fired 1,600 people in February 2026 and opened 800 AI Engineer positions the same week. The salaries on the new roles were 40 percent higher than what the fired engineers were making.
I have watched hundreds of JavaScript developers fail the same interview question for the last three years. The question is not hard. The question is some variation of "explain closures.
Every JavaScript developer knows console.log. It is the first debugging tool you learn and, for most developers, the last one you ever use. I watched a senior developer last month debug a performance issue by adding 47 console.log statements across 12 files, scrolling through hundreds of lines of terminal output, trying to find the one log that showed where the bottleneck was. I
I reviewed a pull request last week that had 47 files changed, 2,300 lines added, and a description that said "refactored user module." It took me 3 hours to review. I found 14 issues. The developer spent another day fixing them.
A developer on my team spent two days debugging a React component that "randomly" showed stale data after a form submission. The component called an API, updated the database, and then read the updated value. Sometimes it worked.
Every JavaScript tutorial teaches you how to use async/await. None of them teach you what happens when three API calls fail simultaneously, a user navigates away mid-fetch, the database connection drops for 200 milliseconds, and your error handler catches a generic
TypeScript 6.0 shipped on March 23, 2026. The announcement post from Daniel Rosenwasser got 5,340 likes, 962 reposts, and 369,000 views on X within 48 hours. That is more engagement than most JavaScript framework releases get in an entire month. But the hype is not about TypeScript 6.0 itself. The hype is about what comes after it.
Last month a single unhandled Promise rejection took down the checkout flow on a production e-commerce application for 47 minutes. The error was a network timeout calling a payment API.
The European Accessibility Act took effect on June 28, 2025. Every digital product sold or used in the European Union must now meet WCAG 2.1 AA standards or face fines. The United States saw a record 4,605 web accessibility lawsuits filed in 2024, up 14% from the year before. Target paid $6 million.
Most developers think WebSockets are solved technology. They learned the API in a tutorial five years ago, built a chat demo, and moved on. Then they get hired at a company with 50,000 concurrent users and discover that everything they know stops working around the 10,000 connection mark. The demo worked. Production doesn't.
I reviewed 340 senior JavaScript developer interviews over the last six months on jsgurujobs.com. The pattern that kept appearing was not about frameworks or syntax. It was about design patterns.
A React web developer with three years of experience averages $135,000 in remote job listings right now. A React developer who also lists React Native on their resume averages $168,000.
GraphQL was supposed to kill REST. That was the narrative in 2019 when every startup and their investor was convinced that REST APIs were legacy technology. Seven years later, REST handles more traffic than ever. G
Prisma 7 shipped in January 2026 with the most dramatic architectural change in the project's history. The Rust engine that powered every query for the last five years is gone. The entire client is now pure TypeScript. Bundle size dropped 90%.
For thirty years, JavaScript developers have been fighting the same battle. The built in Date object is broken. Everyone knows it. Months are zero indexed so January is 0 and December is 11. There is no built in way to work with time zones properly. Parsing dates from strings is inconsistent across browsers. Mutating a Date object changes the original instead of creating a new one, which causes bugs that take hours to find.
Tailwind Labs fired 75 percent of their engineering team in January 2026. The company that builds the most popular utility CSS framework in the JavaScript ecosystem cut three quarters of its engineers, citing the "brutal impact of AI" on development workflows.
Next.js now powers over 900,000 live websites. Vercel reported a 47 percent year over year increase in deployments in 2025. The framework has more weekly npm downloads than React Router, Gatsby, Remix, and Astro combined.
TypeScript officially surpassed JavaScript in new GitHub repository creation in late 2025. Not in overall usage, JavaScript still runs the world, but every new professional React project I have seen in the last twelve months starts with TypeScript. It is no longer a preference. It is the baseline expectation.
Every React developer has had that moment. You build a feature, it works perfectly in development, you deploy it, and then someone on the team opens the performance tab in Chrome DevTools.
The application grows. Components multiply. State becomes scattered across useState hooks like breadcrumbs through a forest. Props drill down through five, six, seven layers of components. Someone suggests lifting state up, and suddenly the top level component has thirty pieces of state that have nothing to do with each other.
The JavaScript runtime wars have reached a turning point. For over fifteen years, Node.js stood alone as the undisputed king of server side JavaScript. Developers never questioned their runtime choice because there was no choice to make. You wanted to run JavaScript outside the browser, you used Node.js. Period.
Evan You, creator of Vue and Vite, unveiled Vite+ at ViteConf 2025 in Amsterdam, marking the first unified JavaScript toolchain that actually works in production. After raising $4.6 million in seed funding led by Accel, VoidZero assembled creators and core contributors from Vite, Vitest, Oxc, and Rspack to build what Rome failed to deliver: a single CLI replacing webpack, Babel, ESLint, Prettier, Jest, and half a dozen other tools that every modern JavaScript project requires.
The framework era is ending. By 2026, 18% of all web page loads already contain Web Components according to Google's Chrome Platform Status, while developers are rediscovering that vanilla JavaScript paired with native browser APIs delivers faster performance and smaller bundle sizes than React ever could. Modern CSS features like container queries, :has(), and view transitions are eliminating entire categories of JavaScript that frameworks once required.
Three major frameworks released game-changing versions within two months of each other, and the performance results will surprise you. After rebuilding the same production application in Svelte 5, React 19, and Vue 3, the winner isn't who most developers expect. Svelte 5's compiler generates bundles 3x smaller than React 19 and renders 60% faster in real-world scenarios. React 19's Server Components solve important problems but don't actually make your apps faster after initial load.
In 2025, front-end development is more competitive than ever. Choosing the right framework for your project can determine its scalability, performance, and developer experience. Three of the most popular options today are Vite, Next.js, and Remix, each excelling in different use cases.
