ECMAScript 2026 was formally approved by Ecma International on June 30, adding Array.fromAsync, Error.isError, Math.sumPrecise, and a handful of other long-awaited features. Google announced LiteRT.js, a browser ML inference library claiming 3-60x speedups over TensorFlow.js via WebGPU and WebNN. On the CSS front, modern anchor positioning and the Popover API are getting solid write-ups that make a real case for deleting overlay JavaScript entirely. ## Content **TLDR:** TypeScript 7's Go-port compiler is getting wider ecosystem coverage today, with Node Weekly confirming the release alongside npm v12 and a CVE dispute from a core maintainer. ECMAScript 2026 was formally approved by Ecma International on June 30, adding Array.fromAsync, Error.isError, Math.sumPrecise, and a handful of other long-awaited features. Google announced LiteRT.js, a browser ML inference library claiming 3-60x speedups over TensorFlow.js via WebGPU and WebNN. On the CSS front, modern anchor positioning and the Popover API are getting solid write-ups that make a real case for deleting overlay JavaScript entirely. --- ## ECMAScript 2026 officially approved with seven new features Ecma International ratified ES2026 on June 30. The additions that will actually change day-to-day code: Array.fromAsync for consuming async iterators without manual loops, Error.isError as a reliable alternative to instanceof across realms, Math.sumPrecise for floating-point sums that don't accumulate rounding errors, and Map/WeakMap getOrInsert to kill the check-then-set boilerplate. Uint8Array Base64/hex conversion and JSON.parse source text access round out the release. These are all stage-4 features, so they're already in recent V8 and SpiderMonkey builds.

The headline numbers: up to 3x faster than TensorFlow.js on CPU, and 5-60x faster when the browser can route work to GPU via WebGPU or NPU via WebNN. It runs .tflite models directly, with PyTorch conversion supported via LiteRT Torch. Ultralytics already ships official LiteRT export for YOLO models. If you're doing object detection, depth estimation, or audio processing client-side and still on TensorFlow.js, this is worth benchmarking.

The API split is real: Radix uses asChild/Slot composition while Base UI uses render props. Base UI has active MUI backing and is closing component gaps fast. The post includes a migration guide for existing shadcn projects. If you're starting a new project or evaluating a Radix migration, the comparison is worth reading before you commit.

Express bumps to v5, Node.js minimum is now 22.15.0, SockJS is gone in favor of native WebSocket, and the source is now native ESM with dual ESM/CJS exports. The spdy HTTP/2 dependency is replaced with node:http2. There's also a security fix that rejects cross-site requests to internal endpoints. If you're running webpack-dev-server in CI or have custom middleware, check the breaking changes list before upgrading.

Worth testing tsgo against your own build first though — at preview it's not yet full parity on the programmatic compiler API and declaration emit, so custom transformer / ts-patch setups can break. ## Similar posts on daily.dev - [Issue \#793: What's new in ECMAScript 2026 — JavaScript Weekly](https://daily.dev/posts/issue-793-what-s-new-in-ecmascript-2026-javascript-weekly-uoyf342wj) · JavaScript Weekly · 2 upvotes · 0 comments - [TypeScript 6.0 is your final warning](https://daily.dev/posts/typescript-6-0-is-your-final-warning-2tbdrcemi) · Bytes by ui.dev · 144 upvotes · 15 comments - [Node Weekly Issue 611: February 12, 2026](https://daily.dev/posts/node-weekly-issue-611-february-12-2026-vobr34fos) · Node Weekly · 7 upvotes · 0 comments --- Tags: [#webdev](https://daily.dev/tags/webdev), [#javascript](https://daily.dev/tags/javascript), [#typescript](https://daily.dev/tags/typescript), [#webgpu](https://daily.dev/tags/webgpu) [View this post on daily.dev](https://daily.dev/posts/typescript-7-lands-in-node-weekly-ecmascript-2026-officially-approved-s21gij5uj) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/typescript-7-lands-in-node-weekly-ecmascript-2026-officially-approved-s21gij5uj","headline":"TypeScript 7 lands in Node Weekly, ECMAScript 2026 officially approved","text":"TypeScript 7's Go-port compiler is getting wider ecosystem coverage today, with Node Weekly confirming the release alongside npm v12 and a CVE dispute from a core maintainer.
