Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Most definitely. A simple subtraction problem? More like a 9 kyu ;)
Probably the solution that makes the most sense between all those I read...
And I learned about Object.keys
i think reduce is more useful!
OMG ! I'm afraid I choose the wrong way...
I was reading the kata test cases to learn how you check if filter() is used, but I can't understand this :Test.assertEquals( Array.prototype.filter_used, true, "Try with filter-method" ); Could you explain where this comes from please ?
Maybe I'm wrong, but I think the real goal of this kata is not to break the code very efficiently, but to find a way to make the tryCode() function remember the last try without writing any external code. If this is the case, it should probably be stated very clearly: "Don't write any code outside of the tryCode() function".
!untrue must be
(1) some kind of paid to the line developer
(2) a software architect
Anyway, thanx for sharing !

This should be 8 kyu IMHO
I really had a hard time finding how to properly initialize the array in the range function, so the map function can do its job.
I don't think this exercise is 7 kyu, at least if one try to do it the functional way.
I had the same problem and I found the solution by looking at what happens when I click on "attempt" with the chrome developer tools. I saw an object like this :
{
...
reason: "TypeError: Reduce of empty array with no initial value"
...
}
So I figured that in my sum function I had to manage the case where the array is empty, and it solved my problem.
