Lucee Server has a very handy feature where the left() and right() functions allow you to pass a negative number which strips that many chars off of the Opposite end of the string.  It's basically turns it into an "all but this many chars" functionality as opposed to "only this many chars".  It's great for stripping something of known length off the start of a string like so:

myString='// { "foo" : "bar" }'
dump( myString.right( -2 ) )
