javascript how to var newclass(in) = oldclass(null, in)?
<p>Excuse me for not using any technical descriptions here as I am new to javascript.  But this is a simple question for anyone learned in javascript.</p>

<p>I am just trying to create a new class that takes only one argument from an existing one that takes two or more arguments.  </p>

<pre><code>var newclass(arg) = oldclass(1,"hello",arg); // newclass is pre-filled with 1 and "hello"
</code></pre>

<p>Therefore I want to essentially pre-fill the arguments so I may only have to pass one argument in. What is the proper way of doing this in javascript?</p>
