Asynchronicity — Anne’s Blog
12 August 2014 There is ever more asynchronicity within the web platform. Asynchronous being some set of steps that could be performed in parallel with JavaScript running in a given environment such as a window or worker. Fetching networked resources, computing crypto, and audio processing, are examples of things that can be done asynchronous. The JavaScript language does not really know about thr
BabelとTraceurでES6末尾再帰最適化を試す - teppeis blog
ちょっと前にBabelに末尾再帰最適化が入って話題になったけど、同じくTraceurにもv0.0.85で最適化が入ったので試してみた。 末尾再帰最適化って何？ 厳密な話はそちらの筋に任せるとして、ざっくりしたストーリーはこんな感じ。 再帰って深くなるとstack overflowになっちゃう 再帰をシンプルなループ（スタックを使わないジャンプ）に変換できればstack overflowを避けられる 一般に末尾再帰であれば再帰をループに変換できる方法が知られている（これが末尾再帰最適化） 末尾再帰とは、関数の最後のステップだけで再帰呼び出しを行うこと 末尾再帰ではない再帰関数でも、CPS変換を使うことで末尾再帰関数に変換が可能 CPS変換とは、関数を結果の値を受け渡すスタイルから継続渡しスタイルに書き換えること つまり、普通の再帰関数 -> CPS変換で末尾再帰化 -> 末尾再帰最適化を適用
最近のjs非同期処理 PromiseとGeneratorの共存 - Qiita
（2015/10/21追記） 記事を書いてから半年経ちましたが、最近はRxの良さを理解したり、ES7のasync/awaitがbabelによって実用的になりつつあったり等、またもやベストプラクティスとはなんだったのか状態です。とはいえ、いまのところPromiseは非同期処理の土台であり続けそうですし、Generatorもasync/awaitへの足がかりとして知っておくことのメリットは大きいかと思いますので、引き続き公開させたままとさせて頂きます。 （追記ここまで） 数ある非同期処理のプラクティスを試してみて、だいたいこれが良いんじゃないかというパターンが固まったので書きます。効用はコールバック地獄からの脱出と結局非同期どれが良いの感の払拭。ES6寄りです。 前提知識 JavaScript Promiseの本 http://azu.github.io/promises-book/ ジェネレ

New: merge() family of functions now get the currently merging key as a 3rd argument, in case merge strategy should alter based on key. IndexedCursor now has push(), pop(), unshift() and shift() to more closely mirror List. Records initialize lazily. Creating a new Record type with Record({foo:"bar"}) involves a small bit of work. For applications with a large amount of Records, lazy initializatio

“We have decided not to integrate the Dart VM into Chrome” | Hacker News
I think Dart is sort of like CoffeeScript in that it was an experiment and influenced a lot of JavaScript standards people.A lot of the features of CoffeeScript are being integrated into JS with ES6 and ES7. The same is actually happening to the unique features of Dart such as typing and SIMD and better modules. Typing is so cool: http://wiki.ecmascript.org/doku.php?id=harmony:typed_objects SIMD i

That's so fetch!
There's been some confusion around the new fetch API recently. Let's clear things up. The first thing you'll notice about fetch is it's a massive improvement on XMLHttpRequest in terms of API design. Here's how to get some JSON using XHR: var xhr = new XMLHttpRequest(); xhr.open('GET', url); xhr.responseType = 'json'; xhr.onload = function () { console.log(xhr.response); }; xhr.onerror = function
