When Vue components retrieve state from it, they will reactively and efficiently update if the store's state changes. You cannot directly mutate the store's state.

Also, what is state in VUE JS?

State is simply an object that contains the properties that need to be shared within the application: This state object only has a numbers array. Mutations are functions responsible in directly mutating store state. In Vuex, mutations always have access to state as the first argument.

Similarly, what is the difference between VUE and VUEX? While the Vue instance has a data property, the Vuex store has State. Both are reactive. And while the instance has computed properties, the Vuex store has Getters , which allow us to access filtered, derived, or computed State. The difference with the Vuex store is that it also has Mutations.
