Vuex is a state management library for Vue.js applications, which provides a centralized store to store and manage the application's state. This state can be accessed by any component in your application and modified in a predictable way through a set of defined mutations. Vuex also enables developers to easily handle asynchronous operations using actions and getters.
Compared to other state management libraries like Redux, Vuex has a simpler and more intuitive API due to its integration with Vue.js. Its reactive nature also makes it very easy to use with Vue components. Additionally, Vuex provides excellent developer tools, including time travel debugging, allowing you to easily track and debug changes to your application's state over time.
