It is a question not an issue. The tests are the same in all languages and 6749 guys passed the kata.

Please read further starting from "However, the standard does not specify how long that "time unit" is".

Please read the kata description carefully: "if you have trouble discerning if the particular sequence of 1's is a dot or a dash, assume it's a dot".
In this particular case you have no way to find out if 111 is a dot or a dash, so assume it's a dot.

I can only repeat what I said some time ago about Java

System.out.println the input (or the size of the given arrays) and your result, then compare that with what the test outputs (note that here in Java tests "actual" and "expected" are swapped but with your output printed you will be able to see what is wrong in your program; it is somehow kind of debugging).
Note that something is wrong in your code otherwise you would not fail but don't give up!!! Cheers!

console.log

how can i print my input and output? i am using javascript.

Please which language? Print your input and your output in your console so you will be able to see your error.
