async-reducer-context/libs/event.js

通过react-context,useReducer替代redux，可扩展支持与redux周边middleware中间件，通过useModel(['key'])可获取state和dispatch，其中useModel已做到获取的属性值变化，组件才会重新渲染，摆脱useContext因context中无关数据导致的重复渲染问题。

var EventEmitter = /** @class */ (function () {
    function EventEmitter() {
        this.take = [];
    }
    EventEmitter.prototype.on = function (callback) {
        this.take.push(callback);
    };
    EventEmitter.prototype.run = function () {
        this.take.forEach(function (callback) {
            callback();
        });
    };
    return EventEmitter;
}());
export default EventEmitter;
