JavaScript Class Syntax

Let's build a JavaScript class syntax from first principles. For the purpose of this exercise, let's assume that the purpose of the class syntax is to add much-needed sugar to common JavaScript idioms.

Let's start with how JavaScript "classes" work today:

// this is a constructor
Person = function() {
 this // `this` is a new instance of Person

Updates

• 04/10/2011 - Updated application.js and application.rb thanks to @rebo's comments

In this article, I will walk through some simple steps to get a [demo app][2] up and running with [Backbone.js][3] and [Sinatra][4] on [Heroku][5].

function forTimeout(array, iterator, delay) {
    void function iteration(index) {
        if (index === array.length) return
        iterator(array[index])
        setTimeout(function () { iteration(index + 1) }, delay)
    }(0)
}

forTimeout([1, 2, 3], function (v) { console.log(v) }, 1000)

# The Script fetches the url from the clipboard,
# so that you only have to select the url in your
# browser and start the script. Works great when
# mapping "xterm -e youtube.sh" to a shortcut, e.g. Meta-Y.

# requires the tools xclip, youtube-dl and mplayer
# it's probably possible to replace xclip with pbpaste on
