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.
Ok, I see now that I got confused by the whole "Passed: 0 Failed: 1" message, thinking that I hadn't passed any test and wondering where the second matrix/test run came from. Thanks a lot for your help and patience! :)
Ok, I may be totally missing something here, but my console.log(matrix.length) produces 3 and 3.
Fair enough and noted. I'll just ask a question next time. Could you tell me though why matrix.length produces two values? Thank you!
Can it be that in TS two matrices/nested arrays are being tested simultaneously instead of just one at a time? Trying to convert the 2D array into a 1D array results in two 1D arrays.
