Answer 1

The biggest difference among other solutions to transfer objects (marshaling) is object references.

For instance, if you use it to transfer a tree:

A

|-B

|-C

in a list {A,B,C}:

B.parent = A C.parent= A

then A is the same object in Javascrit!

On the bad side, if you have complex structures with circular dependencies and lot of objects: A<-B, B<-C, C<-B, C<.A,... it could crash.

Anyway, I use it in a real project used by many hundreds of companies in production to transfer thousands of objects to a single html page in order to draw a complex graph and it works nicely with a good performance.
