concatenate two strings using ``bytes.concat(bytes(s1), bytes(s2))``.
You should use ``bytes`` over ``bytes1[]`` because it is cheaper,
since ``bytes1[]`` adds 31 padding bytes between the elements. As a general rule,
since using ``bytes1[]`` in ``memory`` adds 31 padding bytes between the elements. Note that in ``storage``, the
padding is absent due to tight packing, see :ref:`bytes and string <bytes-and-string>`. As a general rule,
use ``bytes`` for arbitrary-length raw byte data and ``string`` for arbitrary-length
string (UTF-8) data. If you can limit the length to a certain number of bytes,
always use one of the value types ``bytes1`` to ``bytes32`` because they are much cheaper.
