Comprehensive Model Answer
Verified Solution
Props are custom attributes you can register on a component. When a value is passed to a prop attribute, it becomes
a property on that component instance. You can pass those list of values as props option and use them as similar to
data variables in template.
Vue.component('todo-item', {
props: ['title'],
template: '<h2>{{ title }}</h2>'
})
Once the props are registered, you can pass them as custom attributes.
<todo-item title="Learn Vue conceptsnfirst"></todo-item>

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.
