// code defined outside functions
// use var keyword to create a global variable

var xdata = [35,82,97,10,27];  // create/intialize an array
var size = xdata.length;       // .length gets array size, as expected 
var i, j;
var temp;

// don't need to declare a type for variables
// they are auto typed depending on what you put in them

for (i = 0; i < size-1; i++)
   for (j = size-1; j > i; j--)
      if ( xdata[j] < xdata[j-1] )
      {
         temp = xdata[j];
         xdata[j] = xdata[j-1];
         xdata[j-1] = temp;
      }

// output sorted list to browser (instead of console 
// or a window-based system)

// simply print array directly like a variable
document.write( "Output sorted array: ", xdata );
