<h2>Example</h2>

<p>In this example we will remove the element at index 2 (&quot;Stale&quot;), and add a 
new element (&quot;Tove&quot;) there instead:</p>

<table class="ex" cellspacing="0" border="1" width="100%">
  <tr>
    <td>
    <pre>&lt;script type=&quot;text/javascript&quot;&gt;</pre>
    <pre>var arr = new Array(5);
arr[0] = &quot;Jani&quot;;
arr[1] = &quot;Hege&quot;;
arr[2] = &quot;Stale&quot;;
arr[3] = &quot;Kai Jim&quot;;
arr[4] = &quot;Borge&quot;;</pre>
    <pre>document.write(arr + &quot;&lt;br /&gt;&quot;);
arr.splice(2,1,&quot;Tove&quot;);
document.write(arr);</pre>
    <pre>&lt;/script&gt;</pre>
    </td>
</tr>
</table>

<p> 
The output of the code above will be:</p>

<table class="ex" cellspacing="0" border="1" width="100%">
  <tr>
    <td>
    <pre>Jani,Hege,Stale,Kai Jim,Borge
Jani,Hege,Tove,Kai Jim,Borge</pre>
    </td>
</tr>
</table>

<h2>Example</h2>

<p>In this example we will remove three elements starting at index 2 (&quot;Stale&quot;), and add a 
new element (&quot;Tove&quot;) there instead:</p>

<table class="ex" cellspacing="0" border="1" width="100%" id="table3">
  <tr>
    <td>
    <pre>&lt;script type=&quot;text/javascript&quot;&gt;</pre>
    <pre>var arr = new Array(5);
arr[0] = &quot;Jani&quot;;
arr[1] = &quot;Hege&quot;;
arr[2] = &quot;Stale&quot;;
arr[3] = &quot;Kai Jim&quot;;
arr[4] = &quot;Borge&quot;;</pre>
    <pre>document.write(arr + &quot;&lt;br /&gt;&quot;);
arr.splice(2,3,&quot;Tove&quot;);
document.write(arr);</pre>
    <pre>&lt;/script&gt;</pre>
    </td>
</tr>
</table>

<p> 
The output of the code above will be:</p>

<table class="ex" cellspacing="0" border="1" width="100%" id="table4">
  <tr>
    <td>
    <pre>Jani,Hege,Stale,Kai Jim,Borge
