1.To create more than 1 fsm with the same config,
const cfg = {
...
events: {
...
{
name: 'step',
from: 'init',
to: ['a', 'b', 'c'],
condition: function (options) {
const {args:[{instanceid, id}]} = options;
console.log(instanceid(${instanceid}) ID:{id:${id}- method condition was called);
return new Promise(function (resolve, reject) {
resolve(id%3);
});
},
},
...
}
...
}

fsm_(1...n) = StateMachine({...cfg});

2. using those fsm in different concurrent workers, pass the args to the machine
   fsm_(n) .step({instanceid: fsm_(n).instanceId(), id: a_random_num});

concurrent process data by different fsm created above, the condition method will not be called properly and the state machine was broken.
