Babel 5.4 was just released and with it comes support for a new experimental ES7 syntax proposed by Kevin Smith (@zenparsing) and implemented in Babel by Ingvar Stepanyan (@RReverser). Warning: This syntax is highly experimental and you should not use it for anything serious (yet). If you do use this syntax, please provide feedback on GitHub. The function bind syntax introduces a new operator :: w

ES6 In Depth is a series on new features being added to the JavaScript programming language in the 6th Edition of the ECMAScript standard, ES6 for short. Last week I promised a change of pace. After iterators and generators, we would tackle something easy, I said. Something that won’t melt your brain, I said. We’ll see whether I can keep that promise in the end. For now, let’s start with something

Stack Overflow に日本語版ができたとはいえ、やはり英語圏のフォーラムに助けを求めなければならないことは多いと思います。 義務教育で習った英語で内容を読み解くことはできても、英作文となるとなかなか思ったことを表現できず、質問をためらってしまうことがあります。 そこで、実際の海外の掲示板のやりとりの中で一般的なフレーズを集め、どのように書けば自然な英文で質問できるのか考えてみることにしました。 質問の流れは次のような構成を取ることが一般的です。 1. 何をしようとしているのか 2. 何が起こったのか 3. 何を試してみたのか 4. 何を知りたいのか 5. 結びの言葉(省略可) つまり、「こういうプログラムを作っていて、次のようなコードを書きましたが、このようなエラーが起きます。こうしてみても同じでした。何が原因なのでしょうか?宜しくお願い致します。」という順番で文を組み立てていけ
TLDR: If this is used without super (which should be statically analyzable), let it refer to Object.create(new.target.prototype). Otherwise, let super creates what it refers to. I know the reason to force super in derived class's constructor is to make sure this refers to the exotic object the base class might allocate. But I bet in real world, extending base classes who only create ordinary objec

[What Every C Programmer Should Know About Undefined Behavior #1/3 の翻訳です。] LLVMでコンパイルしたコードは、最適化を有効にしているとたまにSIGTRAPシグナルを生成するのはなぜなのか、と聞かれることがある。いろいろ調べたあと、(X86での話だが) Clangは "ud2" インストラクションを生成していたことがわかった。"ud2" は__builtin_trap()が生成するインストラクションと同じものだ。[訳注: #UD例外を発生させる命令。ソフトウェアが#UD例外をハンドルできているかテストするために使われる。つまり、ソースコードが未定義な振る舞いを使っていたから、LLVMはud2インストラクションを生成したのであって、LLVMのバグではない、ということ] こういう問題は幾つかあって、すべて、Cの未定義な振る

Typography has a long and rich history, but much has been lost in the transition to the web. While browser support for typography has advanced a lot in the last couple years, we still have a long way to go. Features print designers take for granted are either nonexistent on the web or have insufficient browser support in order to be useful. Challenges unique to web browsers such as responsive desi
There were some notes, and plans about a 1.0 release. I want to use this issue for any discussion and plans around it and start a complete list of tasks to do before we can release. There is this google doc that was started by @vojtajina and there was #944, which I will close in favor of this issue. Below is an incomplete list of things that need doing in my opinion.

Facebook introduced Flux about a year ago for client-side web application building and since then it has become one of the hottest tech in the web development scene.
