Loving this syntax.

I had no idea this syntax was possible. Very cool!

=>-.. . -.-- .. --.. -.-- ..- ..- -. - --- ...- -.- .... ... ...- .--- -.. .-- .... .-.. .-- --.- -.-. ..-. -.- --. .-.. .-- --. .... -. -- --.- .- ..-. /

Didn't decode correctly - Expected: 'deyizyuuntovkhsvjdwhlwqcfkglwghnmqaf ', instead got: 'deyizyuuntovkhsvjdwhlwqcfkglwghnmqaf'

Isn't 1 halfway between two even numbers (0 and 2)? It should be rounded to 0.

• JS version has no sample tests
• inputs from description should be used in tests too...

        Assert.AreEqual ("I can read morse code",
          Kata.Decode (".. / -.-. .- -. / .-. . .- -.. / -- --- .-. ... . / -.-. --- -.. ."));
          Check this simple test for first char 

This seems to be a duplicate of other katas which are themselves flagged as duplicates or combinations as Voile noted below, for example :

• https://www.codewars.com/kata/morse-code-translate-text-to-and-from-morse-code/discuss/javascript

There are a bunch of them with the same description of same problem with minor variations

• different word breaks
• some are numbers only, some are numbers and letters

There is also a full series on morse code which extends into much harder kata :

• https://www.codewars.com/kata/decode-the-morse-code

Seems too similar to the Decode the Morse Code. I just ran into this myself, creating a kata before realizing it really is almost an exact duplicate of another kata, albeit with stricter performance requirements and thorough random tests etc. Looks like you're in a similar situation.. a better test layout but still the same basic thing. Maybe morph it into something different? Not morse code but Cyrillic or something? Or your own invention, and then add a twist? (We do already have quite a few 'translate the...' katas.)

EmptyEncodeTest check Decode input.

The test case is checking for an uppercase as the first character eventhough the discription states case insensitive. As this was noted three months ago and has yet to be fixed this is another reminder.
