Subject: Re: Escaping characters

In Ruby, there is a distinction between strings that are between  
double quotes and strings in single quotes.
"\\" escapes the necessary characters, and also allows substitution.  
ex: "#{name}" => "Pradeep"
'\\' does not do any of these. ex: '#{name}' => '#{name}'

Single-quoted strings are faster than double-quoted strings.
