<div>
Retrieves regular expression matches in the given text

<div>
Returns an array of groups (with the first group being the full match). If the regex contains the global flag (i.e. <code>/g</code>),
multiple nested arrays are returned for each match. If the regex is global, returns <code>[]</code> if no matches are found,
otherwise it returns null.
