Introduction

a device that can be in one of a set number of stable conditions depending on its previous condition and on the present values of its inputs

Assumptions

• A machine degree of complexity varies with the type and ultimately, the use case.

• A machine holds the current state and data.

• Being stateful or stateless depends on the machine's usage.

• Every action, output function and listener function receives the current data object.

• Mutation happens during actions and output functions.

• The machine's determinism is not verified.
