Update

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 test syntax and test runner.

Get started with Ryan Anklam's Learn JavaScript completely On the Cloud With the JavaScript Koans and Cloud9 IDE

Test 49: About Reflection (topics/about_reflection.js)

Hi!
Thank you for the wonderful things.

There are two the same thing on line 60 and line 59.
I think line 60 is "b.constructor.name".

line59: equals(a.constructor.name, __, "what is the name of a's constructor?");
line60: equals(a.constructor.name, __, "what is the name of b's constructor?");

Array splice test seem broken

Array test seem broken

test("", function() {
    var daysOfWeek = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday'];
    var workingWeek = daysOfWeek.(__, __); // Weird to use  as it removes elements from daysOfweek
    ok(workingWeek.equalTo([]), 'what is the value of workingWeek?');
    ok(daysOfWeek.equalTo([]), 'what is the value of daysOfWeek?');
});

about_operators.js addition and assignment addtion

Nevermind.

Didacto (per README.md) dead?

Looks like didacto is dead again? :(

License required

Hey,

Your Javascript koans are awesome. But you need to license this else its actually difficult to fork or contribute back. This might help (http://choosealicense.com/)[http://choosealicense.com/]

Expected results on topics/about_reflection.js

I'm wondering, what are the expected results on https://github.com/liammclennan/JavaScript-Koans/blob/master/topics/about_reflection.js#L58-L60

I get empty quotes, but i'm not sure if that is what expected, so I searched a little bit and based on https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Function/name I changed locally:

var A = function() {
    this.aprop = "A";
};

var B = function() {
    this.bprop = "B";
};

on top of that file to

function A() {
    this.aprop = "A";
};

function B() {
    this.bprop = "B";
};    

And i get "A" as the expected constructor.name value, which makes more sense to me. If I'm wrong or missing sth. could you explain why?

about_arrays missing result, expected, diff

The About Arrays tests do not display results, expected values, or diffs, unlike tests before and after.

add a test for truthiness of an empty array

Spanish translation

Hi @liammclennan! I found this repository very useful and I've thought to translate it in Spanish language.

So, I will start to translate it now in our fork... I will send you a pull request when is ready.

Jasmine?

I find I like the Jasmine testing framework much more than QUnit. It is possible new students might find it's syntax a little more friendly.

I wonder what the interests is in either converting this to Jasmine or including Jasmine allowing the student to choose which test framework they want. (The later requires duplication of code).

document-ready should be removed

Unfortuanetely the demo on the QUnit documentation seems to suggest using document ready. But QUnit actually uses the window-load event to wait before executing any tests.

I'm going to fix the docs, but wanted to let you know anyway, as this project looks like a great way to learn JS unit testing and QUnit - want to link or maybe even integrate this somehow.

[Error: object is not a function] message: 'object is not a function'

I am getting following error when I am trying to run using IntelliJ IDEA or NodeJS Qunit plugin:

Test 47: About Reflection (topics/about_reflection.js): hasOwnProperty

Hi!

I have a problem with first part of test 47. The solution of ok(keys.equalTo(['__', '__', '__']), 'what are the properties of the array?'); should not be ['0', '1']? Why three elements in the array?

Thanks

Readme.md: Link to http://javascript.didacto.net is dead

Thanks for sharing the koans i really liked them and the readme made me curious about your new project Didacto JavaScript:

If you like JavaScript Koans you might enjoy my newer, more user friendly, project Didacto: JavaScript

But following the link gives me a 502 bad gateway. Is the site just temporarily down or is the project discontinued?
