What is Vuex used for?

Vuex is used for centralized state management in Vue.js applications. It is a pattern and library that facilitate the development of applications with shared state that needs to be reactive.

Main purposes of Vuex:

• Centralization of state: Allows you to put the application's shared state into a single store, making it easily accessible to all components.
• Predictable state changes: Introduces strict rules for changing state through mutations, which simplifies debugging and change control.
• Lightweight and reactive: Integrates with Vue.js and provides reactivity when the state changes.
• Structuring: Allows organizing state, mutations, actions, and getters into modules for large applications.

Vuex includes the following key components:

• State: An object containing the application's state data.
• Getters: Functions to get computed data from the state. They work like computed properties for the store.
• Mutations: Functions for synchronous state changes. The only way to actually change the state in the Vuex store.
• Actions: Functions for asynchronous operations and calling mutations. They do not change the state directly.
• Modules: Allow dividing the store into smaller, modular parts for better organization in large applications.
