Promises in JavaScript can seem a bit daunting at first, but understanding what's happening under the hood can make them much more approachable. In this blog post, we'll dive deep into some of the inner workings of promises and explore how they enable non-blocking asynchronous tasks in JavaScript. I'm still working on making this blog better on mobile devices, mobile browsers don't always render t
While we’re not yet feature-complete, these numbers are representative of the order of magnitude performance improvement you’ll see checking most codebases. We’re incredibly excited about the opportunities that this massive speed boost creates. Features that once seemed out of reach are now within grasp. This native port will be able to provide instant, comprehensive error listings across an entir

JavaScriptでは任意の値を例外としてthrowすることができますが、実際にはErrorのインスタンスをthrowするのが慣例です。 エラーの原因をより正確に説明したいときはErrorを継承するのが望ましいですが、単に継承するのではなく以下のように書くのがオススメです。 class MyError extends Error { static { this.prototype.name = "MyError"; } }その背景について以下で説明します。テーマは以下の3つです。 nameプロパティcaptureStackTracecauseプロパティnameを正しくセットするNode.jsでエラーを表示させると、クラス名が正しく表示されます。 > throw new (class C extends Error {})() Uncaught C [Error]ここで出力されている "C

Today, we are announcing Sandpack 2.0, which introduces Nodebox—a fast Node.js runtime that allows you to run server-side code in any browser. One year ago, we introduced Sandpack, an open-source in-browser bundler that allows you to run live running code examples on your website. We couldn’t have made a better decision. We knew how powerful Sandpack is (it's the bundler that powers CodeSandbox it
We are going beyond repositories, building a developer platform where agents and humans can collaborate, interact, and grow. The birth of a new galaxy in this universe draws near.
Published Feb 05, 2026 We tasked Opus 4.6 using agent teams to build a C Compiler, and then (mostly) walked away. Here's what it taught us about the future of autonomous software development. Written by Nicholas Carlini, a researcher on our Safeguards team. I've been experimenting with a new approach to supervising language models that we’re calling "agent teams." With agent teams, multiple Claude

esm-package.md Pure ESM package The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS. This means you have the following choices: Use ESM yourself. (preferred) Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide. If the package is used in
Vector embeddings have been tasked with an ever-increasing set of retrieval tasks over the years, with a nascent rise in using them for reasoning, instruction-following, coding, and more. These new benchmarks push embeddings to work for any query and any notion of relevance that could be given. While prior works have pointed out theoretical limitations of vector embeddings, there is a common assum
We developed the Privacy Sandbox with the goal of finding innovative solutions that meaningfully improve online privacy while preserving an ad-supported internet that supports a vibrant ecosystem of publishers, connects businesses with customers, and offers all of us free access to a wide range of content.

Skip to the content. Why does this exist? Single sign-on (SSO) is a mechanism for outsourcing the authentication for your website (or other product) to a third party identity provider, such as Google, Okta, Entra ID (Azure AD), PingFederate, etc. In this context, SSO refers to a SaaS or similar vendor allowing a business client to manage user accounts via the client’s own identity provider, withou

この記事について webpack の設定ファイルであるwebpack.config.jsは、TypeScript で書いて Node.js 上で実行できます。しかし、本来であれば TypeScript のソースコードは Node.js では実行できないはずです。 この事が気になった私は、今回その仕組みを調べてみたので、この場を借りてその調査結果を共有したいと思います 💪 参照 記事の概要 概要のみ知りたい人に向けて、以下にこの記事で解説する内容をまとめておきます 👇 webpack-cli では、 rechoir を使って TypeScript を require() できるようにしているよ rechoir は、 ts-node などを使って require.extensions を拡張しているよ ちなみに、 require.extensions は非推奨だよ webpack-cli
Humanity wastes about 500 years per day on CAPTCHAs. It’s time to end this madness2021-05-13 Select all the buses. Click on bikes. Does this photo have traffic lights? As ridiculous as these questions are, you’re almost guaranteed to have seen one recently. They are a way for online services to separate humans from bots, and they’re called CAPTCHAs.

What is ts-blank-space? ts-blank-space is a fast type-stripping compiler that converts TypeScript to JavaScript. It supports a modern subset of TypeScript by erasing the types and replacing them with whitespace. That's it. It is not a type checker and does not perform any other code transformations. The underlying technique can improve build performance and simplify development. The implementation

Pull Request Merge Queue is now available in limited beta. Learn more about the feature and how to request early access. Why a merge queue? Maintaining high velocity and keeping your main branch green can be a challenge today. Many repositories try to do this by requiring all pull requests be up to date with the main branch before merging. This ensures the main branch is never updated to a commit
