Re: Regex Anchors confusion

The second test is looking for a word boundary, followed by a space, followed by a word boundary, followed by the end of the string.

The pattern doesn't match your data. I can't immediately think of a situation where / \b$/ would ever match.

Since \b matches in between a word character and a non-word character, / \b$/ can never match.

Well, technically, \b matches between a word character, and the failure to match a word character (such as the edge of a string). I know you know that. This is for others that are following along at home. {grin}

So, there are four pairs: word-word, word-nonword, edge-word, edge-nonword. \b matches the middle two of those, and \B matches the outer two of those.
