jQuery and its cousins are great, and by all means use them if it makes it easier to develop your application. If you're developing a library on the other hand, please take a moment to consider if you actually need jQuery as a dependency. Maybe you can include a few lines of utility code, and forgo the requirement. If you're only targeting more modern browsers, you might not need anything more tha
This page is the consolidated reference for all the amp modules in a single page for the sake of being 'cmd+f' friendly.

Project goals: Excellent, cross-browser test coverage Independently maintained and versioned Strict semver for versioning Try ver
GitHub: jackfranklin/the-refactoring-tales 読んだ日付: 2015年1月11日 まだ4章の途中までしか書かれてないですが、ウェブ版は無料で読めてPDF版等は買えるようになるようです(6-7章ぐらい予定) The Refactoring Tales - JavaScript Playground またGitHubにソースが公開されています(ウェブページはまだ反映されてない感じのtypoの修正等がありました) 感想 1,2章はフロントのJavaScriptで、jQuery世界を例にjQueryでべったり書いてしまったものをどうやって分けていくかの話。 1章はとても読みやすくて完成度もあるので読んでみるといい気がします、2章のカヌーセルの話はもっと深くやっても良かったような気がします。 縦に並ぶ$を見かけるとつらい感じになりますが、まずは手が出しやすい場
In the last few days of 2014, I resurrected my long-neglected GIF-beatmatching project DJGif to throw a New Year’s party on my rooftop: Ʌbelard playing his first set of 2015 A DJ using Ableton Live, a huge bundle of MaxMSP emitting a UDP stream of beat information (courtesy of the immensely pro Cade), a UDP ➝ WebSockets server, and DJGif pulling hundreds of GIFs off various Tumblrs to beatmatch <x
Smalltalk MVC Translated to JavaScript Published January 3, 2015 in JavaScript, MVC The original Smalltalk MVC is an elegant way to structure an application. Unfortunately, the JavaScript community takes more inspiration from Dr. Frankenstein than from Smalltalk. The community appears to have done its best to saw off many good parts from MVC and bolt on unnecessary ugly bits to create framework mo
この記事はECMAScript 2015の事始めとして、ライブラリをECMAScript 2015で書いて公開するというところから始めるのがいいのではという内容です。 ECMAScript 2015(ES2015)はES6とも呼ばれていてどちらも同じものを指しますが、この記事ではES2015に統一します。 ECMAScriptのバージョンについては次のページを参照してください。 ECMAScript · JavaScriptの入門書 #jsprimer 2018-12-27: 追記 textlint/textlint-rule-helperのmasterはTypeScriptの実装へ変換されています。 Babelの実装はhttps://github.com/textlint/textlint-rule-helper/tree/2.0.1から参照できます Babel から TypeScrip
Introduction The JavaScript core language features are defined in a standard called ECMA-262. The language defined in this standard is called ECMAScript. What you know as JavaScript in browsers and Node.js is actually a superset of ECMAScript. Browsers and Node.js add more functionality through additional objects and methods, but the core of the language remains as defined in ECMAScript. The ongoi
The upcoming SharedWorker API allows to transmit data across iframes and even browser tabs or windows. It landed in Chrome years ago, and not so long ago in Firefox, but it’s nowhere to be seen in IE or Safari. A wildly supported alternative exists that can be used today, but it’s largely unknown. Let’s explore it! I wanted an elegant solution to the following scenario: suppose a human walks into
