<h2><a class='anchor' name='description'>Description</a></h2>
<p>List is a subclass of SequenceableCollection with unlimited growth in size. Although not a subclass of <a href="./../Classes/Array.html">Array</a> or its superclass <a href="./../Classes/ArrayedCollection.html">ArrayedCollection</a> it uses an Array in its implementation and is in many cases interchangeable with one. (List implements many of the same methods as Array.)
<p>Arrays have a fixed maximum size. If you add beyond that size a new Array is created and returned, but you must use an assignment statement or the new array will be lost. (See the <a href="./../Classes/Array.html">Array</a> helpfile.) List has no size limitation and is thus more flexible, but has slightly more overhead.<pre class='code prettyprint lang-sc'>(
x = Array.new(3);
y = List.new(3);
5.do({ arg i; z = x.add(i); y.add(i); });
x.postln; z.postln; y.postln;
)</pre>
<p>Many of List's methods are inherited from <a href="./../Classes/SequenceableCollection.html">SequenceableCollection</a> or <a href="./../Classes/Collection.html">Collection</a> and are documented in those helpfiles.<h2><a class='anchor' name='classmethods'>Class Methods</a></h2>
