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.

I got the impression from the reading I did ( had to do ) that we're being asked for a Julian Day, not a Julian Date. I may be wrong there; if anybody actually knows either way, please chime in.
I didn't know about Julian Days. The description should have contained enough information ( and not necessarily more ) that I would not have had to Google "Julian Date" and read up, esp. the fact that a Julian Day is just a sequential number since a reference date. If you want or need to know more, it's acceptable to have to click through ( a link to Wikipedia would be nice ).
This would be an 8 kyu kata in JavaScript but for the vagaries of
Date. I don't know if it is your intention to have this kata being more about pointing out those vagaries than about Julian dates, in JavaScript. It's not necessarily a problem, I don't really know what to do about it either if you think it is, but it's exceedingly simple to convert dates if you know how to encode them in JS.There are no false tests with
n < 1.There are no random tests.
Sample tests has the wrong function name.
missing edge case type:
test.assert_equals(range_extractor([n]), 'range(n,n+1)')(withn>1 or n<0, ofc)No random tests.
Returning different data types is a bad practice.
In fact, I don't understand what's the point of returning a string instead of an actual
range...
