    <p>A very good technique to help minifiers, is to pass variables into a self invoking function:</p> <pre><code>(function(window, document, $, undefined) { // all of your application logic goes in here }(window, window.document, jQuery)); </code></pre> <p>A minifier will then create shortcuts for the arguments, like <code>a, b, c, d</code>.</p> <pre><code>(function(a, b, c, d) { }(window, window.document, jQuery)); </code></pre> <p>Now, <code>window</code>, <code>document</code> and <code>jQuery</code> (if it's used) and the <code>undefined value</code> are accessed quite often normally. This will help to decrease the filesize even more.</p> <p>A few nice Javascript shortcuts, are described in <a href="http://typeofnan.blogspot.com/2010/11/about-javascript-shortcuts-trickery.html" rel="noreferrer">this <strong>article</strong></a>.</p> <p>For instance, use <code>~~</code> instead of <code>Math.floor()</code>.</p> <p><strike></p> <pre><code>var floored = Math.floor(55.2115); // = 55 </code></pre> <p></strike></p> <pre><code>var floored = ~~(55.2115); // = 55 </code></pre> <hr> <p>Another really neat thing is, that almost all Javascript interpreters convert numbers for you. For instance, we want to have a <code>setTimeout</code> which fires after 3 minutes. Instead of doing it like</p> <pre><code>setTimeout(function() { }, 180000); </code></pre> <p>or <code>60 * 3 * 1000</code>, we can just call:</p> <pre><code>setTimeout(function() { }, 18e4); </code></pre> <p>Which probably makes much more sense, on much bigger numbers, but anyway :-)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
