Question 1/15
😊 Your
answer was correct

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

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.

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({

});
Available answers
Vuex store plugins are integrated by including them in the
plugins
option when creating the store.

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
