redux源码代码实现

function kcreateStore(reducer) { var list = [] var state = reducer(undefined,{})

function subscribe(callback) {
    list.push(callback)
}

function dispatch(action) {
    state = reducer(state, action)
    for (var i in list) {
        list[i] && list[i]()
    }
}

function getState() {
    return state
}

return {
    subscribe,
    dispatch,
    getState
}

}
