Memento pattern

“

- [Instructor] The memento pattern is basically providing temporary state of an object and restoration of that object from a conversion into a different format or whatnot. It is often used into serialization and deserialization of data. In this use case, an object is typically in a JavaScript object, where we need to transmit the data to some type of back-end, where we serialize this object into JSON for streaming it through HTTP protocols. Then, when this object hits the back-end server, or when we get a response back from the server through HTTP, we might need to deserialize the JSON object back into a JavaScript object for consumption into our application. Well, this is basically the memento pattern in action, where the data never loses its accuracy, despite several conversions in between formats.
