game-fsm.js
function on (message) {
return function (msgToEvaluate) {
return msgToEvaluate === message;
};
}
…
playersTurn.to(dealersTurn).when(on("player acted"));
‘when’ function defined in StageJS
Transition.prototype.when = function (guard) {
this.guard = guard;
return this;
};
Who can tell me how these codes work?
