Javascript Promise.all - how to handle all errors [duplicate]

Question

How can I handle errors from other than first promise rejection?

Example:

Promise.all[p1, p2, p3].then(...) .catch((error) => { console.log(error) })

Order of rejection: p1 p2 p3

Is it possible to get errors from p2 and p3?

EDIT: from comments below: is it possible to catch error from specific Promise before passing it to .all? E.g. I want to stay with Promise.all funcionality but log all error cases also

There will be only one rejected promise. No more. You'll receive error for the first one rejected and that's it.

This isn't true. Any or all of the promises may reject, but regardless of how many reject, only the first one's error is mad available to catch.

And you can catch each one before passing to all()

Yes, of course all of them may reject, but i meant that there will be only one error object of one rejected promise.
