 ##### Strings
 
-A fundamental part of creating programs is working with textual data. As in other languages, we use the type string to refer to these textual types. Strings are represented by characters between either a single quote or a double quote. When characters are between double quotes they are interpolated, meaning they have expressions evaluated within them. These expressions start with the dollar character. All strings can span multiple lines.
