For a strict array comparison, check their length and values like so:

var a1 = [1, 2, 3];
var a2 = [1, 2, 3];

array_compare(a1, a2);

function array_compare(a1, a2) {
 if(a1.length != a2.length) {
  return false;
 }
 for(var i in a1) {
  // Don't forget to check for arrays in our arrays.
  if(a1[i] instanceof Array && a2[i] instanceof Array) {
   if(!array_compare(a1[i], a2[i])) {
    return false;
   }
  }
  else if(a1[i] != a2[i]) {
   return false;
  }
 }
 return true;
}
