ESLint's biggest breaking-change release in years finalises flat config, removes eslintrc support entirely, and adds JSX reference tracking. But the bigger story might be what's nipping at its heels.

While ESLint v10 was wrestling with legacy cleanup, the Oxc project shipped a linter 100x faster, a formatter 30x faster than Prettier, and a parser that leaves SWC in the dust. Here's what the JavaScript oxidation compiler actually is.

Vercel, Netlify, Cloudflare, AWS, and Google Cloud all signed the same public contract. Next.js 16.2 makes cross-platform deployment a first-class, documented feature.

As of March 2026, IntelliJ IDEA v2026.1 ships JavaScript, TypeScript, HTML, CSS, and basic React features at no extra cost — features that previously required a paid Ultimate subscription. The catch: Angular, Vue, and advanced debugging still need Ultimate.

The popular dependency and unused-code scanner for JavaScript and TypeScript gets a major overhaul, replacing its TypeScript backend with the Rust-based oxc-parser — and the results are dramatic.

The pure TypeScript NumPy implementation hits a new performance milestone and adds Float16 support, bringing scientific computing in the browser closer to reality.

Two poisoned releases of axios — one of the most widely-used Node.js HTTP client libraries — were published and pulled from npm within hours. Here's what happened, how the attack worked, and what you need to do right now.

Cheng Lou just released Pretext, a pure JavaScript library that measures and lays out multiline text without touching the DOM. Here's why that matters for virtualization, layout control, and AI agents that write UI code.

Bun v1.3.11 drops a 4MB smaller binary, ships Bun.cron for OS-level scheduled jobs, and marks a pivotal moment as the runtime joins Anthropic to power Claude Code and future AI coding tools.

Astro 6.0 and 6.1 land within weeks of each other, bringing an experimental Rust compiler, request-time content collections, a built-in Fonts API, CSP tooling, and deeper Cloudflare integration — all while the framework doubles its adoption for the third year running.

The State of JavaScript 2025 survey shows TypeScript exclusive usage at 40%, Vite satisfaction at 98% versus Webpack's 26%, and Claude doubling its developer share. The ecosystem is maturing rather than churning.

Microsoft ships TypeScript 6.0 as the final release built on the original JavaScript codebase. DOM type updates, improved inference, subpath imports, and a migration flag set the stage for the native Go-based TypeScript 7.0.

The Vite 8 beta drops ESBuild and Rollup in favor of Rolldown, signaling a full Rust-based future for the JavaScript build toolchain. What changes, what breaks, and why it matters.

The State of JavaScript 2025 survey reveals TypeScript usage at an all-time high, Vite crushing Webpack in satisfaction, and growing concerns about Next.js complexity.

Three JavaScript runtimes. Three different philosophies. Independent benchmarks across HTTP throughput, cold starts, and async performance tell a clearer story than marketing ever could. Here's the brutally honest breakdown for developers choosing their next server-side JS platform.

VoidZero's Vite+ promises to unify runtime, package manager, bundler, linter, formatter, and test runner under a single command. We read the announcements, benchmarked the claims, and talked to people using it in production. Here is what we found.

Vue 3.5 arrived with no breaking changes and a set of internals improvements that should make any developer pay attention — 56% less memory usage, lazy hydration, and a stabilized reactive props API.
