等待多个异步函数，但在其中一个函数完成后继续

const promise1 = asyncFunction1();
const promise2 = asyncFunction2();
const promise3 = asyncFunction3();

Promise.all([promise1, promise2, promise3])
  .then(results => {
    // 所有异步函数都已完成
    // 继续执行后续操作
  })
  .catch(error => {
    // 处理错误
  });

async function main() {
  const result1 = await asyncFunction1();
  const result2 = await asyncFunction2();
  const result3 = await asyncFunction3();

  // 所有异步函数都已完成
  // 继续执行后续操作
}

main()
  .catch(error => {
    // 处理错误
  });

const EventEmitter = require('events');

const eventEmitter = new EventEmitter();

async function asyncFunction1() {
  // 异步操作
  eventEmitter.emit('asyncFunction1Complete');
}

async function asyncFunction2() {
  // 异步操作
  eventEmitter.emit('asyncFunction2Complete');
}

async function asyncFunction3() {
  // 异步操作
  eventEmitter.emit('asyncFunction3Complete');
}

eventEmitter.on('asyncFunction1Complete', () => {
  // asyncFunction1 完成后继续执行
});

eventEmitter.on('asyncFunction2Complete', () => {
  // asyncFunction2 完成后继续执行
});

eventEmitter.on('asyncFunction3Complete', () => {
  // asyncFunction3 完成后继续执行
});

asyncFunction1();
asyncFunction2();
asyncFunction3();
