Do you have any ideas?

I'm learning TypeScript coming from Python. Write me a small example that demonstrates interfaces, generics, and async/await — maybe a simple API client that fetches data and returns typed results.

In the TypeScript example you just wrote, explain how the generic type T flows through fetchJson — what happens at compile time vs runtime?

Add error handling to the fetchJson function — implement a retry with exponential backoff for failed requests, and write it to a file called api-client.ts
