Pac-Man is dead simple in any language that fits the same general model as C. There are a bunch of globals representing the position of Pac-Man, the score, the level, and so on. Ghost information is stored in a short array of structures. Then there's an array representing the maze, where each element is either a piece of the maze or a dot. If Pac-Man eats a dot, the maze array is updated. If Pac-Man hits a blue ghost, that ghost's structure is updated to reflect a new state. There were dozens and dozens of Pac-Man clones in the early 1980s, including tiny versions that you could type in from a magazine.

In a purely functional language, none of this works. If Pac-Man eats a dot, the maze can't be directly updated. If Pac-Man hits a blue ghost, there's no way to directly change the state of the ghost. How could this possibly work?

This prelude is a learning environment for 'Smooth CoffeeScript'.

The IPython Notebook consists of two related components:

An JSON based Notebook document format for recording and distributing Python code and rich text.
A web-based user interface for authoring and running notebook documents.

There is lots of information about node.js, but given the rapid pace at which it is developing, it can be difficult for beginners to find good, current information on how to get started. This guide aims to provide exactly that, whilst staying updated with the latest stable version of node.js.

CodeMirror is a JavaScript library that can be used to create a relatively pleasant editor interface for code-like content ― computer programs, HTML markup, and similar. If a mode has been written for the language you are editing, the code will be coloured, and the editor will optionally help you with indentation.

Discover the beauty of functional programming in Coffeescript. The source of this book is a literate markdown program/document which produces this code: CoffeeScript, that translates into JavaScript and produces this output.

Functional is a library for functional programming in JavaScript. It defines the standard higher-order functions such as map, reduce (aka foldl), and select (aka filter). It also defines functions such as curry, rcurry, and partial for partial function application; and compose, guard, and until for function-level programming. And all these functions accept strings, such as 'x -> x+1', 'x+1', or '+1' as synonyms for the more verbose function(x) {return x+1}.

Code School is all about learning by doing. Our educational courses combine video, coding in the browser, and gamification principles to make learning more fun and therefore more effective.

Codecademy is the easiest way to learn how to code.

Eloquent JavaScript is a book providing an introduction to the JavaScript programming language and programming in general.

Any business analytics system dealing with moderate amounts of data can be built following this approach.

Apache CouchDB is the central data store
All data is stored as JSON-LD entities
NoFlo handles all data imports
Analytics based on the data are done with CouchDB map/reduce
Visualization happens with a CouchApp using JavaScript InfoVis Toolkit
