//  Determine whether two arrays are exactly equal 
export function arrEuqalse(arr1, arr2) {
  if (!arr1 || !arr2) {
    return false;
  }
  if (arr1.length != arr2.length) {
    return false;
  }
  for (var i = 0; i < arr2.length; i++) {
    if (arr1.indexOf(arr2[i]) == -1) {
      return false;
    }
  }
  for (var i = 0; i < arr1.length; i++) {
    if (arr2.indexOf(arr1[i]) == -1) {
      return false;
    }
  }
  return true;
}
