Just curious about the different methods of outputting a variable in ruby.

In the ruby Hello World exercise, it's suggested that we output our name variable with:

puts "Hello #{name}"

I skipped ahead, and wrote 

puts "hello" + name

and that worked just fine for me. Just curious about matters of best practice, or if it comes down to preference, or if there is a specific reason to use the suggested method over the way I tried.

The #{name} way is very handy if you don't want to break the string, but works only with double quotes. If you use it with single quotes, it will interpret these symbols literally. Once you start using Rails and possibly other Ruby frameworks, you will use the #{name} way most often.
