Verified Solution
You can install vuex using npm or yarn as below,
npm install vuex --save
(or)
yarn add vuex
In a module system, you must explicitly install Vuex via Vue.use()
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)

You can also install it using CDN links such as unpkg.cpm which provides NPM-based CDN links. Just include vuex
after Vue and it will install itself automatically.
<script src="https://unpkg.com/vue.js"></script>
<script src="https://unpkg.com/vuex.js"></script>
Note: You can use a specific version/tag via URLs like https://unpkg.com/vuex@2.0.0. If you don't mention any
version then it will point to latest version.

Candidate Response Strategy & Interview Tips
- Start with a concise one-sentence summary: Deliver a direct, confident answer first before expanding into nuances.
- Demonstrate real-world trade-offs: Discuss where this approach excels and when you would avoid it in production systems.
- Discuss complexity & edge cases: Proactively explain time/space complexity or boundary conditions (null values, scale limits).
- Prepare for interviewer follow-ups: Technical hiring panels frequently probe deeper into concurrency, backward compatibility, or alternative libraries.
