Comprehensive Model Answer
Verified Solution
Below are the main benefits of React Router V4 module,
- In React Router v4(version 4), the API is completely about components. A router can be visualized as a single component(
<BrowserRouter>) which wraps specific child router components(<Route>). - You don't need to manually set history. The router module will take care history by wrapping routes with
<BrowserRouter>component. - The application size is reduced by adding only the specific router module(Web, core, or native)
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.
