javascript function override
<p>Is it possible to completely override the function callwithargs that accepts some arguments with another new function callwithargs with no arguments?</p>

<pre><code>function callwithargs(a, b, c){
       if(arg.length){
        do this
     }else{
        do something else
    }
    }

function callwithargs(){
  do a new thing
} 
</code></pre>
