You may well be right that a regexp based one is faster (given JS'
lack of efficient string/char manipulation methods), but performance
is one area where intuition often leads astray. One should not try to
guess which is faster, but to measure.
So it would be great to get a performance test to verify which is
faster (and on which JS engines) and by how much.
