Agree

I thought the cipher will be randomly generated. I would've used regex if I had known.

Re-raised as an issue.

No random tests.

Javascript version of Kata seriously lacking in both fixed and random tests

When i submit at first,i find that my code must note the uppercase and lowercase letters.

In my opinion it could be nice to add a test with a randomly generated cipher code in order to avoid solutions with a hard-coded code.

Gotcha, thanks for the feedback. I wanted to take a shot at creating a simple one to try it out, I'll see if I can make the changes you mentioned.
