Based on Edgecase's fantastic Ruby koans, the goal of the Javascript koans is to teach you Javascript programming through testing.

When you first run the koans, you'll be presented with a runtime error and a stack trace indicating where the error occurred. Your goal is to make the error go away. As you fix each error, you should learn something about the Javascript language and functional programming in general.

Your journey towards Javascript enlightenment starts in the app/koans/AboutExpects.js file. These koans will be very simple, so don't overthink them! As you progress through more koans, more and more Javascript syntax will be introduced which will allow you to solve more complicated problems and use more advanced techniques.

In the root folder of dowloaded repository run npm install – than grunt server.

Grunt server will open your browser with address 127.0.0.1:9000

The first error will be in app/koans/AboutExpects.js. Fix it and enjoy with automaticly fefresh page. If you see green light – you can go forward otherwise – fix current test.

The test runner used is Jasmine with a customized report viewer.
