    * Set this Boolean attribute to indicate that the browser should, if possible, execute the script asynchronously. It has no effect on inline scripts (i.e., scripts that don't have the <strong>src</strong> attribute). In older browsers that don't support the <strong>async</strong> attribute, parser-inserted scripts block the parser; script-inserted scripts execute asynchronously in IE and WebKit, but synchronously in Opera and pre-4.0 Firefox. In Firefox 4.0, the <code>async</code> DOM&nbsp;property defaults to <code>true</code> for script-created scripts, so the default behavior matches the behavior of IE&nbsp;and WebKit. To request script-inserted external scripts be executed in the insertion order in browsers where the <code>document.createElement("script").async</code> evaluates to <code>true</code> (such as Firefox 4.0), set <code>.async=false</code> on the scripts you want to maintain order. Never call <code>document.write()</code> from an <code>async</code> script. In Gecko 1.9.2, calling <code>document.write()</code> has an unpredictable effect. In Gecko 2.0, calling <code>document.write()</code> from an <code>async</code> script has no effect (other than printing a warning to the error console).

    * This Boolean attribute is set to indicate to a browser that the script is meant to be executed after the document has been parsed.

Never call <code>document.write()</code> from a <code>defer</code> script (since Gecko 1.9.2, this will blow away the document). The <code>defer</code> attribute shouldn't be used on scripts that don't have the <code>src</code> attribute. Since Gecko 1.9.2, the <code>defer</code> attribute is ignored on scripts that don't have the <code>src</code> attribute. However, in Gecko 1.9.1 even inline scripts are deferred if the <code>defer</code> attribute is set.
