JavaScript OSA

<h2 id="description">Description</h2>
<p>The language is identical to Mozilla's core language, with extensions added via a "Core" object and a "MacOS" object. The MacOS object has methods for obtaining objects that are bound to <a href="/facts/Application_software/YQuj7Kog">applications</a>. This is done via the <a href="/facts/AppleEvents/dkUzzmlE">AppleEvent</a> messaging system, a part of the Macintosh's <a href="/facts/Open_Scripting_Architecture/cc3rc4wD">Open Scripting Architecture</a>.
</p><p>The language was first released in 2001, and was bundled with <a href="/facts/Late_Night_Software/xpXLj9FC">Late Night Software</a>'s flagship product, <a href="/facts/Script_Debugger/Dqek9GMA">Script Debugger</a>. In May 2005, a new "alpha" version of the language was made available for testing. This improved second version of the language was bundled with version 4 of Script Debugger. JavaScript OSA was eventually discontinued due to lack of interest<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> and was dropped from Script Debugger 5 in 2012.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a>
