Oops, I wanted to correct but hit the "send" a bit too early...

That should read:

If you want a regex to test a string starting with the 2 characters \
and n, you don't need to write '/^\\\\n/' - instead, you could write
'/^[\\]n/' : using a character class to represent the single backslash -
while still escaping it once (otherwise the engine would assume it's
the  ] being escaped); that gets rid of at least one level of escaping.
