Question 1/15
😊 Your answer was correct 🙁 Your answer was incorrect
In Vuex terminology, what are 'mutations'?

Available answers

Mutations in Vuex are functions that directly modify the state and must be synchronous to ensure predictability.
Question 2/15
😊 Your answer was correct 🙁 Your answer was incorrect
What are 'getters' in the context of Vuex?

Available answers

Getters in Vuex are used to compute derived state from the store's state, similar to computed properties in components.
Question 3/15
😊 Your answer was correct 🙁 Your answer was incorrect
How does Vuex's time-travel debugging feature work with mutations?

Available answers

Vuex allows time-travel debugging by maintaining a history of mutations, enabling developers to go back to previous states and replay state changes to visualize application behavior.
Question 4/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which of the following describes why namespaced modules are useful?

Available answers

Using namespaced modules in Vuex helps prevent naming conflicts by clearly defining where each action, mutation, and state comes from.
Question 5/15
😊 Your answer was correct 🙁 Your answer was incorrect
What does Vuex use to enforce strict state management rules, preventing accidental modification of state?

Available answers

Vuex provides a strict mode that throws errors if the state is mutated outside of mutation handlers, ensuring a more predictable state management.
Question 6/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is the purpose of Vuex modules?

Available answers

Vuex modules help keep your store organized by dividing it into separate parts, which can be easy to manage and test individually.
Question 7/15
😊 Your answer was correct 🙁 Your answer was incorrect
How do you enable strict mode in Vuex?
const store = new Vuex.Store({
    state: { /* state */ },
    mutations: { /* mutations */ },
    strict: true
});

Available answers

Strict mode can be enabled by setting strict: true in the Vuex store options upon creation.
Question 8/15
😊 Your answer was correct 🙁 Your answer was incorrect
How can you delay or debounce actions in Vuex effectively?

Available answers

Actions in Vuex can implement debouncing through functional libraries or custom debounce functions to control the timing of the dispatch.
Question 9/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is the role of 'actions' in Vuex?

Available answers

Actions in Vuex are designed to handle asynchronous operations and allow for complex logic before committing mutations.
Question 10/15
😊 Your answer was correct 🙁 Your answer was incorrect
When using Vuex plugins, how are they typically integrated with the store?
const myPlugin = store => {
    store.subscribe((mutation, state) => {
        // custom logic here
    });
};

const store = new Vuex.Store({
    plugins: [myPlugin]
});

Available answers

Vuex store plugins are integrated by including them in the
plugins
option when creating the store.
Question 11/15
😊 Your answer was correct 🙁 Your answer was incorrect
How can you dispatch an action in Vuex from a component?
this.$store.dispatch('incrementAsync')

Available answers

To dispatch an action, use
this.$store.dispatch('actionName')
, where 'actionName' is the name of the action.
Question 12/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which Vuex method would you use to replace the store with a new state or module, typically used for hot-reloading purposes?

Available answers

The replaceState method is used to replace the existing state with a new one, often for hot reloading or testing purposes.
Question 13/15
😊 Your answer was correct 🙁 Your answer was incorrect
In Vuex, what is the primary purpose of a 'store'?

Available answers

The primary purpose of the Vuex store is to provide a centralized state management solution where the state is shared across components.
Question 14/15
😊 Your answer was correct 🙁 Your answer was incorrect
What key limitation is addressed by Vuex compared to local state management across multiple components?

Available answers

Vuex addresses data consistency challenges across multiple components by centralizing and sharing state, which is difficult to manage with local state alone.
Question 15/15
😊 Your answer was correct 🙁 Your answer was incorrect
In the Vuex pattern, how does the Flux pattern relate to the usage of Vuex?

Available answers
