It depends on the format you want, e.g.
File.open('path/to/test.txt', 'w') do |f|
f.write(array.join(', '))
end
1. you can use forward slashes (/) even on windows
2. instead of f.write you could use f.puts, f.print, etc.
3. another version is:
f = File.open(',...', 'w')
f.puts ...
f.close
The block version is safer than this as it closes the file
automatically, even in the case of exception within the block.
