Getters is not working and state value cannot be change in Vuex

Question

I am new to VueX. The problem here is :

I cannot use getter to access my state in store.js. I can use this.$store.state.java but I can't use this.$store.getters.semuaJasa, once I change the code using getters, it won't display in the browser.
I can't change the value of state. Even I add more items to the jasa array, the output still four items which I write for the first time.

Here is my full code :

This is my directory tree

I stuck for a few hour, finding some information via google but that doesn't help. I really appreciate for all of your responses. You can also access my github repository if needed Excercise 3

Also there is no error shown both in the CLI and the browser console. Thanks — Philip Purwoko

It might be because you are exporting into a const with a name, rather than as default. Which might be creating it more as a module. Does this.$store.getters['store/semuaJasa'] work by chance? If so, that's what is happening. — innerurge1

Please try console.log ur this variable on ur component where you call the getters like what i do below, maybe you doesn't understanding the javascript scoping. Because i've do exactly what you do and it's work. Good luck!

computed: {
        allJasa() {
            return this.$store.getters.jasas;
        },
        cek: () => this,
        cekHot() { return this; },
    },

    mounted() {
        console.log({
            allJasa: JSON.parse(JSON.stringify(this.allJasa)),
            cek: this.cek,
            cekHot: this.cekHot,
        });
    },

see console output from what i do

This is what happened :

I don't realize that I have duplicate store.js in same folder with main.js folder and inside the store folder. In main.js I do import { store } from './store/store' which mean I import the const named variable from the store.js inside the store folder, and it is working normally.

But in the text editor, I actually editing the other store.js that not in the store folder. So, there is no error shown because there is no error. I am just too much confused and don't realize what I am doing. So now I replace the store.js inside the store folder with the other one that I open in the text editor and everything is ok.

Thanks for all of your response, I really appreciate.
