How do I join two files on a newline?

When I run cat 1.txt 2.txt > result.txt, I want result.txt to have a linebreak between the end of the contents of 1.txt and the beginning of the contents of 2.txt. How do I do this?

One of many options is:

echo | cat 1.txt - 2.txt > result.txt

The - argument says 'accept standard input' and the echo provides the new line

This option only works cleanly for 2 files. If you are actually looking at many files etc then for example:

(cat 1.txt; echo; cat 2.txt; echo; cat 3.txt) > result.txt

Would work; It's worth noting this spawns more cat processes.
