Server chosing

I please you again to define variables one time, before it usage. In this example it looks like you define two variables with this same name. This can be confused for many ppl, cauze in "C" language variables defined inside {} have life scope only inside it.

```
var test = [];
if( ... ) 
  test = null;
```

no:
```
if( ... )
   var test = null;
else
  var test = 5;
```
