Remove empty "" strings from array String[]

Hi Everyone. What is the BEST method for removing items from an array? I have a String[] variable, and I need to remove all the "" (empty lines from it).

 var linesToCheck : String[];
 var lines : String[];

 linesToCheck = script.text.Split( '\n'[0] );

   // Remove any empty lines from script
   for ( var line in linesToCheck )
   {
         if ( line != "" )
            lines.Add( line );
    }
