Computation is implemented by one-to-one Pattern-Matching and Substitution.
Croquet's unique technology ensures bit-identical *Computation* in each participants' local browser, reducing network traffic and latency.

⇒ Top-Level Logic ⇒ Computation page is intended to serve as an example of how a `Journal` class creates a `journal` instance with `title` and `story`,
{ "title": "Computation", "story": [], "journal": [ { "type": "create", "item": { "title": "Computation", "story": [] }, "date": 1651225765617 } ] }
and the `title` and `story` are copied up one level so that they are stored before the `journal` and evolve at the same level as the `journal` instance.

# Principle of Computational Equivalence
Almost all processes that are not obviously simple can be viewed as computations of equivalent sophistication (Wolfram 2002, pp. 5 and 716-717). mathworld 
More specifically, the principle of computational equivalence says that systems found in the natural world can perform computations up to a maximal ("universal") level of computational power, and that most systems do in fact attain this maximal level of computational power. Consequently, most systems are computationally equivalent. For example, the workings of the human brain or the evolution of weather systems can, in principle, compute the same things as a computer. Computation is therefore simply a question of translating inputs and outputs from one System to another.
