Here:

• Kata Creator docs
• Kata Best Practices
• Kata Best Practices (google doc)
• codewars js test framework, github

I didn't see any other sources.

OK, I've updated the description to include a note regarding the limitation on the loop { block } syntax.

So I tried this kata with as many different kinds of loops as I could think of. It works with all of these:

# while statement
# while modifier
# until statement
# until modifier
# for statement
# enumerable each

The only way I could induce the 5000 iteration loop limit was using the loop keyword.

I found that in this kata there is discussion of the same problem using the loop keyword.

What syntax were you using when you got the error?

Codewars has timelimit 4 seconds AFAIK. Seen these number somewhere in docs or at forum. But it may be out of date.

Do you know if the loop limit is documented somewhere? Obviously not all loops are affected. I want to be accurate when I update the description.

Why?

Maybe it was Christmas Day when this solution was submitted ?
