<p>This:</p>

<pre><code>&lt;script type="text/javascript"&gt;
    alert("Hello world!");
&lt;/script&gt;
</code></pre>

<p>And this:</p>

<pre><code>&lt;script&gt;
    alert("Hello world!");
&lt;/script&gt;
</code></pre>

<p>seem to accomplish the same thing (at least in chrome, firefox, ie), so, what is the difference? why should I put those extra 25 characters?</p>
