LOL, in my posting the last sentence says "It should be "k mg s". There appears to be only one space between k and m, when I copy to notepad. When I edit the post, there are two spaces. I guess the same thing happened in the example.
(2 spaces in edit mode) "k mg s"
(1 spaces in edit mode) "k mg s"
This is a nice behavior, thx for making the Kata anyway. It was good fun.

The space was there but quite invisible, I modified the string, enclosing it with backticks. Thanks for your post!

I gues meteogish talks about your example in the Kata description, "I was going fishing that morning at ten o'clock". The code for this string is shown in the example as "c nhsoI\nltiahi \noentinw\ncng nga\nk mg s\n\voao f \n\v'trtig". Every word has 7 characters, except the fifth word "k mg s", which has 6 characters. There is a space missing. It should be "k mg s".
Cheerio.

No answer?

I don't understand what you are saying because I don't see any assert string beginning with "c nhsoI\nltiahi \noentinw\ncng nga...". Could you be more precise?
Where do you see that? What was the string to code? Did you take the Javascript kata?
