javascript - Can the Vuex instance name only be store?

Question

Why const variable name = new Vuex.Store({});
You cannot get the defined data by using this.$ variable name, but what if the variable name is store?

Answer 1

const a = new Vuex.Store({})
Object.defineProperty(Vue.prototype, '$a', {value: this.$store})

But this is superfluous

Answer 2

Refer to this official example:

In fact, if you change store to another name, it will have no effect.
