Type Alias: Cookie

Cookie: null | string | number | ReadonlyJSONValue & object

A cookie is a value that is used to determine the order of snapshots. It needs to be comparable. This can be a string, number or if you want to use a more complex value, you can use an object with an order property. The value null is considered to be less than any other cookie and it is used for the first pull when no cookie has been set.

The order is the natural order of numbers and strings. If one of the cookies is an object then the value of the order property is treated as the cookie when doing comparison.

If one of the cookies is a string and the other is a number, the number is fist converted to a string (using toString()).
