marketEvent();  Helper.log: Il parametro includeFormattedState e la logica condizionale all'interno della funzione potrebbero essere semplificati? La formattazione dello stato potrebbe essere gestita separatamente, rendendo la funzione log più generica?  La versione B che propongo log: function(type, data) {
    var template = this.messages[type];
    if (template) {
        var message = this.formatMessage(template, data || {});
        Log(separator + message);

    }
}   puo' sostituire la versione A all'interno del codice?     log: function(type, data, includeFormattedState) {
        includeFormattedState = (typeof includeFormattedState !== 'undefined') ? includeFormattedState : true;
