I am sorry if this is a duplicate, so far I couldn't find the same question.

I have an Object with various methods in my __proto__ member. Let's call the type of this object myObjectType.

Later on I have to do a JSON.stringify(myObjectType). The problem is that then when I build my object from the previous obtained JSON string the type of my Object is plain Object, I lost all the methods I had.

Does any one see why ?

search google for javascript object serialization.

GSerializer library

There's no standardized way of incorporating functions into JSON data. You can do something yourself — that is, write your own JSON serializer that incorporates functions according to some convention — but with straight standard JSON you get numbers, strings, booleans, and null, plus of course objects with named properties and arrays. No functions, just data.

I'd highly remend Douglas Crockford's libraries:
