Comprehensive Model Answer
Verified Solution
Yes, vuex requires Promise. If your supporting browsers do not implement Promise (e.g. IE), you can use a polyfill
library, such as es6-promise using npm or yarn.
npm install es6-promise --save # NPM
yarn add es6-promise # Yarn
After that import into anywhere in your application,
import 'es6-promise/auto'

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.
