This is a regular expression. Basically
\smatches whitespac characters and replaces them with"".edit:
/ ... /marks the regex.^\s+Take 1or more whitespaces at the beginning of the string.\s+$Take 1 or more whitespaces at the end of the string./gDont stop at the first match, but find all matches – “global flag”
