    • N - indicates a newly added property/element
    • D - indicates a property/element was deleted
    • E - indicates a property/element was edited
    • A - indicates a change occurred within an array
  • path - the property path (from the left-hand-side root)
  • lhs - the value on the left-hand-side of the comparison (undefined if kind == 'N')
  • rhs - the value on the right-hand-side of the comparison (undefined if kind == 'D')
  • index - when kind == 'A', indicates the array index where the change occurred
  • item - when kind == 'A', contains a nested change record indicating the change that occurred at the array index
