According to this regular expression reference:
\b: matches at the position between a word character (anything matched by \w) and a non-word character (anything matched by [^\w] or \W) as well as at the start and/or end of the string if the first and/or last characters in the string are word characters.
The /g applies the regular expression globally to what ever you are using (instead of stopping after the first occurrence that regex matches). For more information on global matching see the Advanced regular expression resource.
