I try to use the less of AI on this exercies but I don't think that is not crucial to known how to create a RegExp.

because ranks cannot be changed, are shared across all languages, and have been deflating over time (this kata is 12 years old)

Why is this 5 kyu, I saw some more complicated stuff to be marked 7 kyu or even 8 kyu that required dynamic allocation and custom structures.

A test string like "⅕⒈äʐΔ٠" should catch most of these non-ascii issues (alpha, decimal, digit, numeric)

Solved, delete the default comment.

Is there a safe way to add comments at any line?

BF cannot get the correct input when the code just ,.

eg. abc\0 -> c
eg. \0 -> ÿ

Simple Regular Expression Kata

If someone is as confused as I am and thinks that there is an issue in the kata's JavaScript tests, trust me: there are NO issues.

this is not what is happening. your code returns true for an empty string, while the expected value is false. Your print the input string, but since it's empty and you did not add delimiters, you cannot see it and you think the input was the previous one.

the tests cannot find your function if you change its name; don't do that
