Bacon.js Tutorial Part I : Hacking With jQuery
This is the first part of a hopefully upcoming series of postings intended as a Bacon.js tutorial. I'll be building a fully functional, however simplified, AJAX registration form for an imaginary web site. This material is based on my presentation/hands-on session at Reaktor Dev Day 2012 where I had to squeeze a Bacon.js intro and a coding session into less than an hour. I didn't have much time to
Understanding JavaScript Inheritance - Alex Sexton
So someone shoulder-taps you and asks you to explain the concepts behind JavaScript Inheritance to them. In my eyes you’ve got a few options. The Terminology Play You mention that it’s prototypal inheritance, not prototypical and pretty much gloss over the rest, comfortable in your superiority in terminology. You may go as far as saying “Objects just come from other Objects because there aren’t an
YeomanでフロントエンドとREST APIサーバーを同時に開発する方法 - bathtimefish's blog
先月のHTML5など勉強会で、Yeoman超入門を発表したときに、Yeomanはフロントエンド開発専用にlocalhostサーバー立ち上げるからサーバーサイドとの同時開発はちょっと工夫がいるよね〜みたいな話題があって、参加されてたnode.jsに詳しい方からhttp-proxyつかってapiの部分リダイレクトかけたらいいよみたいな方法を教えてもらった。 なるほどそれは便利だなと思って実際書いてみたら手軽に使える感じにできたので書いておきます。ちなみに今週水曜日にGoogle Developers Liveに出演してYeomanのことを喋らせていただく機会に恵まれたので、その時の参照にも使えるかと思って。（ライブのスライドはこちら） Yeomanは $ grunt server で開発用のWebサーバーを起動することができる。デフォルトで http://localhost:9000/ 以降フ

I know jQuery. Now what?
I gave this talk: I know jQuery. What now? at jQuery UK 2013 (video of the talk), but instead of my usual approach of post-it explosion on my desk, I wrote a post first, and created the slides from the post. So here is my (fairly unedited) quasi-ramble on how I used jQuery, and how I'm looking at where I'm using native browser technology. Addition resources As this post was also the content for a
2013年前半におけるスクリプト言語のバージョンに関する調査 - Sarabande.jp
2000年代後半は Ruby、2010年代は JavaScript のベストプラクティス本がたくさん見られるようになった。 ベストプラクティス本が出版されるということは新しいバージョンに移行するための準備がなされていることも意味する。 JavaScript のバージョンアップに関して IE が大きな障害になっていたが、MicroSoft が自動的なアップグレードを設定したり、2014年の Windows XP サポート打ち切りに備えて、Google のように IE8 以下のサポートを打ち切る企業が登場し、新しいバージョンが受け入れられる状況が進んでいる。2013年前半において EcmaScript 6 の機能実装はあまり進んでいない。 Ruby に関しては、Ruby 1.8 と Ruby 1.9 の隔たりが大きいことが問題になっていたが、Ruby 1.9 と 2.0 の際はあまり多くないと

Callbacks are imperative, promises are functional: Node's biggest missed opportunity – The If Works
The nature of promises is that they remain immune to changing circumstances. Frank Underwood, ‘House of Cards’ You will often hear it said that JavaScript is a ‘functional’ programming language. It is described as such simply because functions are first-class values: many other features that define functional programming – immutable data, preference for recursion over looping, algebraic type syste
