Optimize multiple asynchronous function call-CodePudding

Given those two pieces of code :

async function waitAll() {
    await call1();
    await call2();
    await call3();
}

And

function callPromises() {
    Promise.all([promise1, promise2, promise3]).then(/* .... */)
}

What is the most optimized way to call all my async methods ? My opinion is that Promise.all in this situation is faster but I cannot find any answer treating about it.

Of course I am open to any solution that would be better than the two I provided.

Thanks for reading

CodePudding user response：

If the calls are not dependent on each other:

async function callPromises() {
  await Promise.all([call1(), call2(), call3()]);
}
