关于javascript:使用Promiseasync-await每隔1秒打印数组元素

      function sleep(interval) {        return new Promise(resolve =>          setTimeout(() => resolve(interval), 1000)        );      }      async function stepPrint(n) {        for (let i = 0; i <= n; i++) {          console.log(i);          await sleep(i * 10000);        }      }      stepPrint(5);
