    <p><code>Array</code> is an efficient, tail-growable random-access
collection of arbitrary elements.</p>

<h1>Common Properties of Array Types</h1>

<p>The information in this section applies to all three of Swift&#39;s
array types, <code>Array&lt;Element&gt;</code>, <code>ContiguousArray&lt;Element&gt;</code>, and
<code>ArraySlice&lt;Element&gt;</code>.  When you read the word &quot;array&quot; here in
a normal typeface, it applies to all three of them.</p>
