What are the `<Router>` components of React Router v6?
Assesses fundamental understanding of React conventions, runtime behavior, and memory/performance considerations.
Hiring managers look for precision, avoidance of ambiguous jargon, and ability to explain trade-offs under real production conditions.
React Router v6 provides below 4 <Router> components:
<BrowserRouter>:Uses the HTML5 history API for standard web apps.<HashRouter>:Uses hash-based routing for static servers.<MemoryRouter>:Uses in-memory routing for testing and non-browser environments.<StaticRouter>:Provides static routing for server-side rendering (SSR).
The above components will create _browser_, _hash_, _memory_ and _static_ history instances. React Router v6 makes the properties and methods of the history instance associated with your router available through the context in the router object.
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.
