Not a good practice to use exceptions for implementing normal program flow.

"this" keyword is not needed here. Only if you have same spelling on param and property but you have one starting with capital letter and one starting with non-capital letter

i like ur katas

JS fuck :)

both of you can fill in a field "Clan" in account settings with same name, and u will see him on dashboard page

its ok, problem solved

Ah ok. Can you show me your code?

yes i know it, but basic tests already work
so i need a way to get information about hidden tests which fail

Not sure if you're still interested in the hint, but try to think about what will happen if your function is called with these parameters:
nextItem([1,2,3,4], 4);
Good luck!

You can add some print-statements to the test yourself, like this:

      next 7 [1..10000] `shouldBe` (Just 8)
      print "passed test1"

That way the terminal will print a test is done when it has succeeded.
Good luck!

hey guys, im new to haskell
basic tests work, but i got error on submit tests
is there any way to see which test fails?

thank you, now its clear

Theses tests test if function value gives correct results when provided as last argument. (Remember value argument may be a value or a function :
You may assume:

• at least 2 arguments (d1and value) are provided
• each d argument will be a positive integer
• value argument may be a number, a string, a boolean, ...

If value is a function then the result of this function will be attribued to the item.

)

In theses cases some values are expected in very first/last items of resulting array (1st item of 1st subarray, last item of last subarray), it seems your solution doesn't return expected values.

Hope it helps!
