Generally with Ruby, methods with the ‘!’ are destructive, and modify
the
receiver in place:

s = “foobar\n”
=> “foobar\n”
s.chop
=> “foobar”
s
=> “foobar\n”
s.chop!
=> “foobar”
s
=> “foobar”

…here you can see ‘chop’ returns a modified copy, leaving ‘s’ intact,
whilst ‘chop!’ modifies ‘s’ directly.

HTH,
