Comprehensive Model Answer
Verified Solution
A directive can take any valid javascript expression. So if you want to pass multiple values then you can pass in a
JavaScript object literal.
Let's pass object literal to an avatar directive as below
<div v-avatar="{ width: 500, height: 400, url: 'path/logo', text: 'Iron Man' }"></div>
Now let us configure avatar directive globally,
Vue.directive('avatar', function (el, binding) {
console.log(binding.value.width) // 500
console.log(binding.value.height) // 400
console.log(binding.value.url) // path/logo
console.log(binding.value.text) // "Iron Man"
})

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.
