 <p>
 A Dart string is a sequence of Unicode character codes.
 You can use either single or double quotes
 to create a string:
 </p>
 
 {% highlight dart %}
 var s1 = 'Single quotes work well for string literals.';
 var s2 = "Double quotes work just as well.";
 var s3 = 'It\'s easy to escape the string delimiter.';
 var s4 = "It's even easier to just use the other string delimiter.";
 {% endhighlight %}
 
 <p>
 You can put the value of an expression inside a string
 by using ${<em>expression</em>}.
 If the expression is a variable,
 you can skip the {}.
 </p>
 
 {% highlight dart %}
 var s = 'string interpolation';
 
 assert('Dart has $s, which is very handy.' ==
        'Dart has string interpolation, which is very handy.');
 assert('That deserves all caps. ${s.toUpperCase()} is very handy!' ==
        'That deserves all caps. STRING INTERPOLATION is very handy!');
 {% endhighlight %}

 <h4> StringBuffer methods </h4>
 
 <p>
 To programmatically generate a string, you can use
 <a href="http://api.dartlang.org/dart_core/StringBuffer.html">StringBuffer</a>.
 A StringBuffer doesn't generate a new String object
 until toString() is called.
 </p>
 
 {% highlight dart %}
 var sb = new StringBuffer();
 
 sb.add("Use a StringBuffer ");
 sb.addAll(["for ", "efficient ", "string ", "creation "]);
 sb.add("if you are ").add("building lots of strings.");
 
 var fullString = sb.toString();
 
 assert(fullString ==
     'Use a StringBuffer for efficient string creation '
     'if you are building lots of strings.');
 
 sb.clear();  // All gone!
 assert(sb.toString() == '');
