I have an application in which i am storing values in localstorage. By default my first value is null due to which i am getting error to run the code so i want to remove the first element and continue the processes. can anyone please help me how to remove first element from list?

Piece of my code is below:

```
var str = localStorage.getItem("appidlist");
var mySplitResult = str.split(",");
for(var i = 0; i < mySplitResult.length; i++) {
   if (.....) {
      .
      .
   }    

}

```

where **str** returns null,1,2,3,.....
I hope my question is clear can anybody help me.
