Tests have been updated to be more random, thanks for the help.

Random tests aren't random; they are entirely predictable.

Values, and ideally length, of the input list should be random, and k should be random or at least randomised.

No fixed tests. Copy the example tests to the submit tests. There should be absolutely no possibility of failing the example tests but passing the random tests.

No test with k = 1. That means testing the specs is incomplete; k = 1 is legal according to the specs.

With this Node function, you can create a linked list like this: new Node(1, new Node(2, new Node(3)))

This is incorrect. next is not a parameter; .next has to be set after node creation.

Random test has been updated. Thanks for contributing.

There are no random tests. The describe block says the tests are random, but they're all fixed.

should return dates that fall on Wednesday and also fall on the 4th week of every month within the range from 2022-07-01 to 2022-07-31 when mode is 3

expected [ '2022-07-20' ] to deeply equal [ '2022-07-27' ]

So the kata actually expects "4th Wednesday of the month" rather than "Wednesday on the 4th week of the month".

the function should return dates that fall on the specified daysOfWeek and also fall on the nthWeek of every month within the range from dateFrom to dateTo.

There are no universal definitions on how to count "n-th week of a month", unlike "n-th week of a year", which is well-defined in ISO standard. So you need to clarify what definition you're using.

Random tests have been updated. Thanks for contributing.

Sample test has been updated as instructed. Thanks for contributing.

The random test has been updated; should the number of test cases be considered?

The description has been updated as instructed. Thanks for contributing.

Node API should be specified in the description.

Also, if results need not be constructed from Nodes, but any recursive Object construct with data and next properties will do ( as the Example tests show ), this should also be clarified in the description.

2nd sample test includes 2022-01-01, which is incorrect.

You should mention if dateTo is inclusive or not.
