Interviewer Expectations for this Question
01
Core Competency
Assesses fundamental understanding of Vue.js conventions, runtime behavior, and memory/performance considerations.
02
Evaluation Criteria
Hiring managers look for precision, avoidance of ambiguous jargon, and ability to explain trade-offs under real production conditions.
Comprehensive Model Answer
Verified Solution
No, it is not recommended. Computed properties should be synchronous. But if you still use asynchronous actions
inside them, they may not work as expected and can lead to an unexpected behaviour.
For example, the below usage of async/await is not recommended,
async someComputedProperty () {
return await someFunction()
},
Note: If you still prefer to use async computed properties for some reason then you can consider using
additional plugin such as vue-async-computed.

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.
