Hi,

Duplicate, as pointed below. @evanrh: do not close the issue, it's aslo a general flag and has meaning outside of the scope of your kata itself.

also, for further use (on different kind of tasks ;) ):

• try to not test some requirements only in the full test suite. Here: no example test with the index
• if you try to mimic the original, why no tests on the array parameter?
• note that mimicking builtins generally results in kata of very low interest.
• the random tests are rather bad, for several reasons:
  • reduce is not tested
  • the callbacks are fixed
  • only 1 single random test
  • the size of the input arrays is fixed
• the mutation tests:
  • they are in the random test section => have nothing to do here
  • they are not testing that the input has not been mutated, but that the output is different from the input

Cheers

should provide the index to the callback function

Could you elaborate further on this point? I don't understand what the kata is asking me to do (should I pass the index to the function as a parameter or...?)
