It doesn't seem to work when using vuex. $store.commit for the first time

I want to assign values to store in the root instance and then get these values in the subcomponent. However, it does not seem to be able to assign a value to store in the root instance.

var store = new Vuex.Store ({

) 
state: {
    paramInfos: []

},
mutations: {
    initParamInfos(state,paramInfos) {
        state.paramInfos = paramInfos;
    }
},
actions:{ 
}

}); 

function(){
var self=this;
self.$store.commit("initParamInfos", data);
}

in devtool, it is an arrary in base. After
commit, it becomes an object that can be expanded wirelessly all the time.

Is there no function in

actions

to commit in actions

then dispatch this action

is roughly the following routine. I suggest you take a look at the syntax of vuex 

var store = new Vuex.Store({
    state: {
        paramInfos: []
    },
    mutations: {
        initParamInfos(state,paramInfos) {
            state.paramInfos = paramInfos;
        }
    },
    actions:{ 
        getInfo({commit},data) {
            commit('initParamInfos',data)
        }
    }
});
function initData(){
    let mydata = [1,1,1,1];
    this.$store.dispatch('getInfo',mydata);
}

well, I think I know why. I didn't write it correctly when taking the value. I forgot to add state.
this.$store.paramInfos;
this.$store.state.paramInfos;
but why devtool is such a presentation is still not clear.
