<h1>slice</h1>
<h2>Summary</h2>
<p>Returns a section of an array.</p>
<h2>Syntax</h2>
<pre><code>slice( start , [ end ])
</code></pre>
<dl>
<dt><strong>start</strong></dt>
<dd>Required. The beginning of the specified portion of arrayObj.
</dd>
<dt><strong>end</strong></dt>
<dd>Optional. The end of the specified portion of arrayObj.
</dd>
</dl>
<h2>Examples</h2>
<p>The following examples show how to use the slice method. In the first example, all but the last element of <code>myArray</code> is copied into <code>newArray</code>. In the second example, only the last two elements of <code>myArray</code> are copied into <code>newArray</code>.</p>
<pre><code class="js"><span class="hljs-keyword">var</span> origArray = [<span class="hljs-number">3</span>, <span class="hljs-number">5</span>, <span class="hljs-number">7</span>, <span class="hljs-number">9</span>];
<span class="hljs-keyword">var</span> newArray = origArray.slice(<span class="hljs-number">0</span>, -<span class="hljs-number">1</span>);
<span class="hljs-built_in">document</span>.write(origArray);
<span class="hljs-built_in">document</span>.write(<span class="hljs-string">"<br/>"</span>);
newArray = origArray.slice(-<span class="hljs-number">2</span>);
<span class="hljs-built_in">document</span>.write(newArray);
<span class="hljs-comment">// Output:</span>
<span class="hljs-comment">// 3,5,7,9</span>
<span class="hljs-comment">// 7,9</span>
</code></pre>
<h2>Remarks</h2>
<p>The <strong>slice</strong> method returns an <strong>Array</strong> object containing the specified portion of arrayObj.</p>
<p>The <strong>slice</strong> method copies up to, but not including, the element indicated by end. If start is negative, it is treated as length + start , where length is the length of the array. If end is negative, it is treated as length + end where length is the length of the array. If end is omitted, extraction continues to the end of arrayObj. If end occurs before start , no elements are copied to the new array.</p>
