Having understood what json is, I want to compare it with something and only a serialized object comes to mind. But I have long been tormented by the question, which is time to ask - is it possible to store the serialized object in a file on the server. If so, which file extension is best stored.
Addition:
@ShockWave : Thank you so much! But I have a few more questions - I see the lines again :) what makes you ask - is it possible to serialize an object in as3 into a binary array and transfer it to the server and write to something? That is, if the object is serialized in xml, then as far as I know, this is very bad especially for mobile devices (it eats up a lot of memory), json would be preferable, but as it turned out, it is just like the xml string, the value of which then needs to be converted to types (I'm talking about simple types). I didn’t ever do it myself, but I heard that objects can be serialized into binary formats that are transmitted over the network faster and when deserializing they retain property types and in general the object itself can be reduced to a specific type. And I want to know about the binary serialization as follows: is it possible to save a binary array on the server, is it much faster transmitted over the network (compared to xml) and did you or perhaps read somewhere about comparing the speed of deserialization of binary data compared to the speed of string conversion json to an object and casting the types of this object using the second optional parameter of the parse method? text in italics
