The regular expression /[?/]/ matches either '?' or '/' character. In JavaScript, a regular expression is written between two forward slashes / and can be used with the split() method to split a string into an array based on a specified pattern.
For example, if the string "a?b/c" is split using the regular expression /[?/]/, it will result in the following array:
["a", "b", "c"].
In the same way, If the string is "a?b/c&g$k" and the regular expression is /[?/&$]/, the result of splitting the string using this regular expression will be:
["a", "b", "c", "g", "k"]
