Question 1/15

What key limitation is addressed by Vuex compared to local state management across multiple components?

Select your answer

Vuex removes the need for direct DOM manipulation for UI updates.

Vuex handles view component animations more fluently than local state.

Vuex provides a shared state management solution that removes props and events for data passage between components.

Assorted methods for handling user events in the store.

Functions that modify the state in Vuex.

Selectors that manage routing inside Vue components.

Question 3/15

How can you access a Vuex getter from a Vue component?

computed: {

    }
}

Select your answer

Using

this.$store.state['getterName']

directly.
