How can I wait for multiple async functions to complete simultaneously? Promise.all but using async await

But I dont want to use Promise.all I know this can be done without using Promises My example is:

const getBettingBonuses = async () => {
  return await fetch('http://localhost:3001/bonuses')
}

const getCasinoBonuses = async () => {
  return await fetch('http://localhost:3002/bonuses')
}

const getBettingBonuses = async () => {
  return await fetch('http://localhost:3001/bonuses')
}

const getCasinoBonuses = async () => {
  return await fetch('http://localhost:3002/bonuses')
}

But I want them to start fetching at the same time Sorry for not specifying I want to call them both at the same time, and wait until both of them finish

Yes but then async await came into play, and instead of using Promise.all().then you could do this in a cleaner way with try catch

Sorry for wasting your time gristoi, you helped me remember what I needed from what you said

async function inParallel() {
   const promise1 = printNumber1();
   const promise2 = printNumber2();
   const number1 = await promise1;
   const number2 = await promise2;
}

async function inParallel() {
   const promise1 = printNumber1();
   const promise2 = printNumber2();
   const number1 = await promise1;
   const number2 = await promise2;
}
