Update ====== > If you like JavaScript Koans you might enjoy my newer, more user friendly, project [Didacto: JavaScript](http://javascript.didacto.net/) JavaScript Koans is an interactive learning environment that uses failing tests to introduce students to aspects of JavaScript in a logical sequence. The inspiration for this project comes from the Edgecase Ruby Koans and the book 'Javascript: The Good Parts'. Open the file jskoans.htm in your favourite browser and make the tests pass. The koans use the [Qunit](http://qunitjs.com/) test syntax and test runner. Get started with Ryan Anklam's [Learn JavaScript completely On the Cloud With the JavaScript Koans and Cloud9 IDE](http://blog.bittersweetryan.com/2011/08/learn-some-javascript-completely-on.html)
