As we know, using memento design pattern, we can restore an object to its previous state. I want to modify this to "restore the object to any of its previous states" depending on the requirement. So, let say there are 5 states of object like this -
S1 -> S2 -> S3 -> S4 -> S5
The current state of object is S5. Now, based on some dynamic requirement, I may need to restore its state back to S2. Can it be done with Memento or there is a different design pattern for this altogether. I am trying to do this in Javascript.
