V8 is Google’s open source JavaScript engine. Chrome, Node.js, and many other applications use V8. This article explains V8’s bytecode format — which is actually easy to read once you understand some basic concepts. This post is available in Chinese, translated by justjavac. Ignition! We have lift-off! Interpreter Ignition is part of our compiler pipeline since 2016.When V8 compiles JavaScript cod

This book is a balanced, pragmatic look at FP in JavaScript. The first edition is now complete. Read here online for free, or: "Functional-Light JavaScript" explores the core principles of functional programming (FP) as they are applied to JavaScript. But what makes this book different is that we approach these principles without drowning in all the heavy terminology. We look at a subset of FP fou

Functional Programming in JavaScript is all the rage right now, with new libraries, languages, and transpilers popping up everywhere. You might be thinking, “How do I make this radical paradigm shift?” The answer is, you don’t have to. Not right away anyhow (or ever), and not completely. A Functional JavaScript programming style can have it’s advantages but you don’t need to go all in to benefit f

Before ECMAScript 2015 object literals (also named object initializers) in JavaScript were quite elementary. It was possible to define 2 types of properties: Pairs of property names and related values { name1: value1 } Getters { get name(){..} } and setters { set name(val){..} } for computed property values Sadly, the object literal possibilities match into a single example:

Webブラウザで高速な演算を可能にする低水準言語asm.jsと、WebAssembly詳解ーasm.jsの仕組みとコーディング例 清水智公（Mozilla） 連載の第１回目は asm.jsの紹介と、asm.jsが導入された背景を概観しました。 Just in Timeコンパイルによって高速にJavaScriptを実行できるようになりましたが、立ち上がりが遅い、やり直しが発生する、コンパイルによって一時的に負荷が向上する、といった問題が残されています。 これを解決するためにプログラムの実行を行うより前にネイティブコードへとコンパイルするAhead of Timeコンパイルを導入したいのですが、JavaScriptは柔軟すぎて効率の良いネイティブコードを出力することが難しい、という問題がありました。 asm.jsはこの問題に一定の解をあたえるものとなります。今回はそのasm.jsがどのようなも

Standard Gestures ZingTouch provides six standard gestures that are completely customizable. Note: These demos are best viewed on a touch capable device. A tap event is a quick start and end of an input. Tap gestures can be configured with the amount of time inbetween a start and end, and the number of inputs it requires. Emits interval - a time measured in milliseconds between the start and end o

Years ago, I was working on a project that needed to be adaptive. Essentially, the software needed to learn and get better at a frequently repeated task over time. I’d read about neural networks and some early success people had achieved with them, so I decided to try it out myself. That marked the beginning of a life-long fascination with AI. AI is a really big deal. There are a small handful of
