	`1271`	+O código acime vai exibir `finish` antes de exibir `object`. Porque `await` espera pela funcão `sleep` `resolve`, mesmo se a sincronização de código estiver seguida, ele não executa antes do código assíncrono ser executado.

	`1273`	+A vantagem do `async` e `await` comparado ao uso direto da `Promise` mente em manipular a cadeia de chamada do `then`, que pode produzir código claro e acurado.
	`1274`	`+`
`1271`	`1275`	The above code will print `finish` before printing `object`. Because `await` waits for the `sleep` function `resolve`, even if the synchronization code is followed, it is not executed before the asynchronous code is executed.
`1272`	`1276`
`1273`	`1277`	The advantage of `async` and `await` compared to the direct use of `Promise` lies in handling the call chain of `then`, which can produce clear and accurate code. The downside is that misuse of `await` can cause performance problems because `await` blocks the code. Perhaps the asynchronous code does not depend on the former, but it still needs to wait for the former to complete, causing the code to lose concurrency.
