javascript - Wait for all different promise to finish nodejs (async await)

Question

I am currently waiting for all the promise to finish sequentially like this:

(async() => {
  let profile = await profileHelper.getUserData(username);
   let token = await tokenHelper.getUserToken(username);
   console.log(profile);
   console.log(token);
   return {profile: profile, token: token};
})();

But this way, profile and token executes sequentially. Since both are independent of each other, I want both of them to be executed independently together. I think this can be done using Promise.all, but I am not sure of the syntax and I could not find any help as well.

So my question is how I can convert above api calls to run together and then return the final output.

Answer 1

(async() => {
  const [ profile, token ] = await Promise.all([
    profileHelper.getUserData(username),
    tokenHelper.getUserToken(username)
  ]);

  return { profile, token };
})();
