AI translates the explanation and quiz text while preserving code and answer scoring.

`async` functions always return a Promise. `await` pauses execution until the promise settles, allowing standard `try...catch` blocks for error handling.

js
async function fetchAccount(addr) {
  try {
    return await rpc.getAccount(addr);
  } catch (err) {
    console.error("Lookup failed", err);
  }
}

  3. 3. Answer the quiz without scrolling back — that is the real check.
  4. 4. Read every explanation, even for the answers you got right.
