using async with javascript forEach

Question

I have an array of emails

emails.forEach(email => sendEmail(email)); --> 1

function2();

sendEmail is an asynchronous function I want function2 to be invoked only after line 1 gets completed

How can I achieve this?

`Promise.all(emails.map(email => sendEmail|(email)).then(() => { function2() });` — Roberto Zvjerković, Mar 04 '21 at 14:17

How can I achieve this?

Don't use forEach. Either use a normal for loop, and await each call, or if you want to run them in parallel use map and await Promise.all.

My preference would be:

async function sendAllEmails(emails) {
    await Promise.all(emails.map(email => sendEmail(email)));
    function2();
}
