Fetching data with await

Every data fetch goes through the same three steps: you request the data, wait for it to arrive, then display it. The await keyword turns the waiting into an ordinary line of code instead of a chain of then calls.

Here we use api(), a mock function that behaves exactly like fetch: it returns a promise that resolves a moment later. The only difference is that it doesn't need a network, so what you learn here is exactly what you'll write with fetch.

And remember: any function that uses await has to be async.
