Are these really different functions? jQuery.extend()
<p>The jQuery documentation covers the function jQuery.extend()s twice, giving it different definitions.  The first relates to extending the jQuery object itself:  <a href="http://docs.jquery.com/Core/jQuery.extend#object" rel="nofollow">http://docs.jquery.com/Core/jQuery.extend#object</a>.  The second relates to extend an input argument: <a href="http://docs.jquery.com/Utilities/jQuery.extend" rel="nofollow">http://docs.jquery.com/Utilities/jQuery.extend</a></p>

<p>Are these two usages of the same function, or are these actually different functions?  I presume its the same function, but then I wonder why its documented twice as different functions.</p>
