如何使嵌套循环仅在异步函数解析后才继续，或者如何将".then“扩展到作用域之外

async function nestedLoop() {
  for (let i = 0; i < 10; i++) {
    await new Promise((resolve) => setTimeout(resolve, 1000)); // 模拟异步操作
    console.log(`外层循环：${i}`);
    
    for (let j = 0; j < 5; j++) {
      await new Promise((resolve) => setTimeout(resolve, 1000)); // 模拟异步操作
      console.log(`内层循环：${j}`);
    }
  }
}

nestedLoop();

function outerFunction() {
  let outerResolve;
  const outerPromise = new Promise((resolve) => {
    outerResolve = resolve;
  });

  async function nestedLoop() {
    for (let i = 0; i < 10; i++) {
      await new Promise((resolve) => setTimeout(resolve, 1000)); // 模拟异步操作
      console.log(`外层循环：${i}`);
      
      for (let j = 0; j < 5; j++) {
        await new Promise((resolve) => setTimeout(resolve, 1000)); // 模拟异步操作
        console.log(`内层循环：${j}`);
      }
    }

    outerResolve(); // 解析外部Promise对象
  }

  nestedLoop();

  return outerPromise;
}

outerFunction().then(() => {
  console.log("嵌套循环执行完成");
});
