V8 JavaScript engine
Show navigationWhat is V8?V8 is Google’s open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows, macOS, and Linux systems that use x64, IA-32, or ARM processors. V8 can be embedded into any C++ application.

Liftoff: a new baseline compiler for WebAssembly in V8
Show navigation V8 v6.9 includes Liftoff, a new baseline compiler for WebAssembly. Liftoff is now enabled by default on desktop systems. This article details the motivation to add another compilation tier and describes the implementation and performance of Liftoff. Logo for Liftoff, V8’s WebAssembly baseline compilerSince WebAssembly launched more than a year ago, adoption on the web has been stea
JSエンジン「V8」はバージョン6で世代移行を終える ── Google I/O 2017レポート
JSエンジン「V8」はバージョン6で世代移行を終える ── Google I/O 2017レポート 川田寛（ピクシブ株式会社） ChromeやNode.jsで利用されているJavaScriptエンジン「V8」に、8年の歴史の中でも大きな変化が訪れました。8月3日にリリースされたバージョン6.1で、数年かけて進めてきたJavaScriptコンパイラーが世代交代を終えました。詳しい話は、V8のブログでも語られていますが、ここでは大きなトピックであるコンパイラーの世代交代についてお話します。 なお、この動きについては、昨年に開かれたカンファレンス「BlinkOn 6」でも語られており、Google I/O 2017でも、Seth Thompsonによるセッション「V8, Advanced JavaScript, & the next performance frontier」によって紹介されてい
V8 ❤️ Node.js · V8
Node.js’s popularity has been growing steadily over the last few years, and we have been working to make Node.js better. This blog post highlights some of the recent efforts in V8 and DevTools. Debug Node.js in DevTools #You can now debug Node applications using the Chrome developer tools. The Chrome DevTools Team moved the source code that implements the debugging protocol from Chromium to V8, th
Hello, world! · V8
Welcome to the V8 developer blog! Historically, the V8 team has published blog posts that appeal to the wider web development audience on the Chromium blog. In order to deliver more in-depth posts especially targeted to the hardcore coder and virtual machine enthusiasts out there, we’ve spun off this V8-specific blog. Big-ticket items will continue to be posted to the Chromium blog, but we hope yo
runtime.js – JavaScript library operating system for the cloud
Overview runtime.js is an open-source library operating system (unikernel) for the cloud that runs JavaScript, can be bundled up with an application and deployed as a lightweight and immutable VM image. It's built on V8 JavaScript engine and uses event-driven and non-blocking I/O model inspired by Node.js. At the moment KVM is the only supported hypervisor. It tries to be compatible with npm modul

a closer look at crankshaft, v8's optimizing compiler — wingolog
Continuing in my series of articles on V8, Google's JavaScript engine, in this article I'd like to take a closer look at V8's optimizing compiler, with a focus on the Hydrogen intermediate language. brief summary As my readers might recall, Crankshaft is the marketing name of V8's optimizing compiler. It complements the "full" compiler by optimizing hot functions, while ignoring uncommon cases. It
Improved V8 external arrays support and nodejs Buffer type - mraleph
Recently V8’s optimizing pipeline (Crankshaft) got full support for external arrays (aka WebGL typed arrays). One of core NodeJS types - Buffer - is exposed to JavaScript code as an external unsigned byte array so I decided to do a small unscientific benchmark to see the improvement with my own eyes: var LONG_STRING = "qwertyuiop"; for (var i = 0; i < 13; i++) LONG_STRING += LONG_STRING; // force
Big Sky :: 今更ながらGoogle v8でembedする方法を紹介してみる。
最近どのブログでも node.js ばかりでもう飽き飽きしてる皆さんこんばんわ。 node.js 面白いですよね！ェ node.js ってアプリケーションを作る側(つまりライブラリを使う側)からすると、Web周りの便利なライブラリが既に色々あって、そのライブラリが一体どうやって動いてるのか気にすることってあんまり無いかと思います。 pure javascriptな物ならばコードを読むのは簡単です。ただしやれる事に限りがあります。node.js はGoogle製のJavaScript Engineであるv8をベースに作られているのですが、このv8はアプリケーションに組み込むのに適した構成になっていて、関数テンプレートやインスタンス、プロトタイプという各機能がC++のクラステンプレートで上手く表現出来ているライブラリです。Spidermonkeyも確かに扱うのは簡単なのですが、僕からすると若干
