I don't understand #{ }

Hi there,

I'm new to ruby and rails. I'm going through a few tutorials and I got
the updated agile book. One thing I keep seeing which hasn't quite
been properly explained is something like this:

puts "Hello #{name.capitalize}!"

At one place it stated that the {} merely insert a string into a
string - I assume like concatenation. However the # has not been
explained. Do the # and {} go together?

Yes, they do go together. It just callse to_s on the result of any ruby
code between #{ and }.
