Fixed.

When a kata is solved more than 500 times in a language, its test cases are locked and no longer editable.
Also because that string is part of the expected output, changing it would render all solutions wrong, I wouldn't change it because of that either.

function func(){

//...

};

You mean a closing semicolon as above? And just so I know, does it affect the solution?

There's an extraneous semicolon. Technically there's a top-level empty statement after the function.

Nothing wrong with semicolons in JS.

Language?

Thanks. Is it better now?

You did not answer what is supposed to serve as the data.

Find the most common data type and the amount of times that data type is found in the input array. Then with that Array['type', count], Use that to return a hmac-sha256 signature. Also, I updated the Description.

This is a suggestion

You're absolutely right. Thanks for pointing that out!

leviathan, thanks, I've just updated the description.

Alright, I'll remove it.

Thanks for the suggestion.
