Promise.all() Alternative that allows failure? [duplicate]

Answer 1

You could do something like this:

function allSkippingErrors(promises) {
  return Promise.all(
    promises.map(p => p.catch(error => null))
  )
}

This will resolve all the Promise objects with errors to a null in the resulting array. You could also keep the Error object using .catch(error => error), to detect failures at the end, or resolve to an object with { status, result, error } properties.
