Details

The Promise.any proposal (bug 1568903) adds a new kind of built-in error (AggregateError: https://tc39.es/proposal-promise-any/#sec-aggregate-error-object-structure). AggregateErrors are similar to the existing built-in errors with the exception of:

  • The AggregateError constructor must be called with an iterable value as its first argument.
  • AggregateError.prototype has an errors getter-only accessor. This accessor returns an array of aggregated errors.

Promise.any and AggregateError are currently Nightly-only!
