ES Proposal spec-compliant shim for AggregateError

es-aggregate-error

ES Proposal spec-compliant shim for AggregateError. Invoke its "shim" method to shim AggregateError if it is unavailable or noncompliant.

This package implements the es-shim API interface. It works in an ES3-supported environment, and complies with the proposed spec.

Most common usage:

var assert = require('assert');
var AggregateError = require('es-aggregate-error');

var oneError = new RangeError('hi!');
var otherError = new EvalError('oops');
var error = new AggregateError([oneError, otherError], 'this is two kinds of errors');

assert.deepEqual(error.errors, [oneError, otherError]);
assert.equal(error.message, 'this is two kinds of errors');

AggregateError.shim(); // will be a no-op if not needed

assert.ok(new globalThis.AggregateError([]) instanceof AggregateError);
