EventSourcing for Angular Repository actions reflows

example.js

(function (exports) {
    function EventBus() {
        this.handlers = [];
    }

    EventBus.prototype.push = function (event) {
        foreach (idx in this.handlers) {
            if (this.handler[idx].canHandle(event)) {
                this.handler[idx].handle(event);
            }
        }
    };

    EventBus.prototype.register = function (handler) {
        this.handlers.push(handler);
    };

    exports.EventBus = EventBus;
}());

(function (exports) {
    function FormulaRepository(eventBus) {
        this.eventBus = eventBus;
        this.formulas = [];
    }



    FormulaRepository.prototype.addFormula = function (formula) {
        this.formulas[formula.id] = formula;

        this.eventBus.push({
            name: 'formula-was-added',
            data: formula
        });
    };
}());

(function (exports) {
    function FormulaController(eventBus, $scope) {
        eventBus.register({
            canHandle: function (event) {
                return event.name === 'formula-was-added' ||
                    event.name === 'formula-was-modified' ||
                    event.name === 'formula-was-removed';
            },
            handle: function (event) {
                $scope.$apply();
            }
        });
    }
}());

foreach on line 7 causes an error. Are you thinking of PHP? Should "for" be used?
