Can I somehow create a function that looks like .toUpperCase()? : <p>Instead of using</p>

<pre><code>function functionName(arg){
arg = 1;
}
name(arg);
</code></pre>

<p>I want to use something like the .toUppercase() function</p>

<pre><code>function functionName(){
this = 1;
}
arg.name();
</code></pre>

<p>Is this possible?</p>
