Assesses fundamental understanding of React conventions, runtime behavior, and memory/performance considerations.
02

Comprehensive Model Answer
Verified Solution
It is recommended to name the component by reference instead of using displayName.
Using displayName for naming component:
export default React.createClass({
displayName: "TodoApp",
// ...
});
The recommended approach:
export default class TodoApp extends React.Component {
// ...
}
also
const TodoApp = () => {
//...
};
export default TodoApp;
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.
