Worzone, Yepnope, JSHint
Worzone
Worzone (GitHub: raimohanska / worzone) by Juha Paananen is a game written using Microsoft’s Reactive Extensions for JavaScript. There’s also a blog post about game programming with Microsoft’s RX library in which Juha explains some of the concepts behind reactive programming in JavaScript.
Yepnope
Yepnope (GitHub: SlexAxton / yepnope.js) by Alex Sexton and Ralph Holzmann is a script loader. I realise there’s a million script loaders, but this one caught my eye because it’s got a great site and documentation.
It can be used to load JavaScript or CSS. The example on the site looks like this:
yepnope({
test : Modernizr.geolocation,
yep : 'normal.js',
nope : ['polyfill.js', 'wrapper.js']
});
The test property is used to determine if the yep scripts should load, else the nope scripts will be loaded instead.
The library ships with a test suite, and the author notes it works very well with Modernizr:
Currently yepnope is being included in special builds of Modernizr, because it’s such a good companion to a feature testing library. The output of Modernizr is a fantastic input to yepnope.
It also supports plugins:
Yepnope was designed to be customizable. There are a few simple hooks throughout the loading process that allow you to inject code and change settings around on the fly. There are two main ways to do this: Prefixes and Filters.
JSHint
JSHint (GitHub: jshint / jshint is a fork of Crockford’s JSLint. The website allows you to test it out, but I recommend that you download jshint.js and use it locally.
It currently supports browsers, Node, and Rhino, so you should be able to integrate it with your existing projects.
