javascript – 如何在维护执行顺序的同时减少异步等待关键字的使用

async function foo() {
  await this.getAsync();
  await this.getAsyncTwo();
  await this.getAsyncThree();
  await this.getAsyncFour();
}

看看foo有多个await调用,有没有办法简单地保持执行顺序？

我希望有可能写出类似的东西

async function foo() {
  await 
   this.getAsync(), 
   this.getAsyncTwo(), 
   this.getAsyncThree(), 
   this.getAsyncFour();
}

要么

async function foo() {
  await 
   this.getAsync() 
   .this.getAsyncTwo() 
   .this.getAsyncThree()
   .this.getAsyncFour();
}

解决方法:

这将保证您希望的顺序执行顺序.

async function foo() {
  const functions = [this.getAsync, this.getAsyncTwo, ...];

  for (let func of functions) { 
    await func();
  }
}
