7. 手写bindActionCreators

/**
 * 
 * @param {*} actionCreators  action创建函数或者对象
 * @param {*} dispath store上面的分发方法
 */
export default function bindActionCreators(actionCreators, dispath) {
    if (typeof actionCreators === 'function') {
        getAutoDispatchAction(actionCreators, dispath);
    } else if (typeof actionCreators === 'object') {
        const autoActionObject = {};
        for (const key in actionCreators) {
            if (Object.hasOwnProperty.call(actionCreators, key)) {
                const action = actionCreators[key];
                autoActionObject[key] = getAutoDispatchAction(action, dispath);
            }
        }
        return autoActionObject;
    }
    else {
        throw TypeError('action must be an object or function meas an action')
    }
}
function getAutoDispatchAction(action, dispatch) {
    return function (...arg) {
        const autoAction = action(arg);
        dispatch(autoAction);
    }
}
