I've been attempting to divide the string using two different separators, like so:
"some-str_to_split".split(/-|_/)
It successfully splits the string based on both "-" and "_". However, Webstorm is issuing a warning:
Single character alternation in regex
Keep in mind that the pattern -|_ matches either a hyphen or an underscore, with the regex engine prioritizing the hyphen over the underscore during matching. This process may involve backtracking, where the engine tries different options until a match is found. On the other hand, using [-_], known as a character class, allows the regex engine to execute a faster search by eliminating the need for backtracking.
Therefore, the warning serves as a suggestion to optimize your pattern for better performance. While the difference may be minimal when dealing with only two alternatives, it becomes more noticeable when there are numerous possibilities (e.g., 100+).
