プロトタイプ＝見本となるオブジェクト - rikubaのブログ
JavaScriptを始めたころはprototypeオブジェクトが何なのかよく分からなかったけど、その名の通り「見本」あるいは「原型」なんだと分かれば、コンストラクタ関数とprototypeオブジェクトの関係は単純だと思える。 例として、人を表すオブジェクトを考えてみる。姓を表すlastNameプロパティと、名を表すfirstNameプロパティ、そしてそれらをつなげた文字列を返すgetFullNameメソッドを定義する。 var person = { firstName: '右京', lastName: '杉下', getFullName: function () { return this.lastName + ' ' + this.firstName; } }; さらに違う人物を表すオブジェクトを作ることになったとする。 var another = { firstName: '享',

Promises
Motivation Consider the following synchronous JavaScript function to read a file and parse it as JSON. It is simple and easy to read, but you wouldn't want to use it in most applications as it is blocking. This means that while you are reading the file from disk (a slow operation) nothing else can happen. function readJSONSync(filename) { return JSON.parse(fs.readFileSync(filename, 'utf8')); } To

Dependency injection in JavaScript
I like the quote that the programming is all about managing complexity. Maybe you've heard that the computer world is a giant construction of abstractions. We simply wrap things and produce new tools over and over again. Just think for a minute. The languages which you use have build-in functionalities and they are probably abstracted functions of other low level operations. It's the same with Jav

Falafel, Source Rewriting, and a Magicial Assert
A couple of weeks ago, I wrote about how to do some basic static analysis of Javascript source code using Esprima. This post is a follow up where I demonstrate how to write a program to transforms Javascript source code using an Esprima-based library - falafel. Hello, Falafel Falafel is an AST traversal library like estraverse. If you've read my previous article, this is familiar territory. Instea
Ember JS – An In-Depth Introduction — Smashing Magazine
The :user_id part is called a dynamic segment because the corresponding user ID will be injected into the URL. So, it will look like /users/3/edit, where 3 is the user with the ID of 3. You can define either a route or a resource. Keep in mind that a resource is a group of routes and that it allows routes to be nested. A resource also resets the nested naming convention to the last resource name,
