// Import the state machine library
const StateMachine = require('state-machine');

// Define the states
const states = {
  STATE_A: 'stateA',
  STATE_B: 'stateB',
  STATE_C: 'stateC'
};

// Define the transitions
const transitions = {
  [states.STATE_A]: {
    'eventA': states.STATE_B,
    'eventB': states.STATE_C
  },
  [states.STATE_B]: {
    'eventA': states.STATE_A,
    'eventB': states.STATE_C
  },
  [states.STATE_C]: {
    'eventA': states.STATE_A,
    'eventB': states.STATE_B
  }
};

// Define the initial state
const initialState = states.STATE_A;

// Create the state machine
const stateMachine = new StateMachine({
  initial: initialState,
  transitions
});

// Example usage
stateMachine.addListener('transition', (event, from, to) => {
  console.log(`Transitioned from ${from} to ${to} with event ${event}`);
});

stateMachine.sendEvent('eventA'); // Transitions from STATE_A to STATE_B or STATE_C
stateMachine.sendEvent('eventB'); // Transitions from the current state to another state
