JavaScript querySelectorAll
<p>A tutorial I'm working on has the following code with the following comment. I don't understand...</p>

<p>i) the comment, specifically, why it says "all second table cells."  What does "second" mean? This isn`t proper English</p>

<p>ii) what is it looking for exactly when it says <code>td + td</code>? The program is about taking data from a table, so would <code>td + td</code> pick out anything between html table tags <code>&lt;td&gt;&lt;/td&gt;</code> for example?</p>

<pre><code>//use querySelector to find all second table cells
var cells = document.querySelectorAll("td + td");
</code></pre>
