They are functionally the same. This answer was made when template literals weren't widespread yet, but today they'd be preferred since they help with readability.

Thats right

The /../ part of the code represents a Regular Expression (RegEx) that looks for any 2 types of characters. If the length is even, When it comes time to check for the last character (i.e. the underscore) it will not be able to find another character after it, and thus won't add it to the resulting array.

I get confused when the string is even, why the match method doesn't match the underscore character?

haha @ the output comment, i had the same question

Very nice (and fast) solution.

Excellent solution

Yes. So is ToList.

clever solution

By far the best solution in terms of both clarity and performance (in my tests it's almost 10 times faster than the solution with list comprehension).

To learn software, of course. The only thing I've refused to learn is statistics.

Why do you bother with a software education website if you refuse to learn anything?

Wow! How did you manage that?
