es-shimsdisposablestack 
An ESnext spec-compliant DisposableStack, AsyncDisposableStack, Symbol.dispose, and Symbol.asyncDispose shim/polyfill/replacement that works as far down as ES3.
Its root auto entrypoint also provides SuppressedError, via the suppressed-error package.
This package implements the es-shim API “multi” interface. It works in an ES3-supported environment and complies with the proposed spec.

const assert = require('assert');
require('disposablestack/auto');

const error = new SuppressedError();
assert.ok(error instanceof Error);
const stack = new DisposableStack();
const asyncStack = new AsyncDisposableStack();
// examples of stack methods
stack.dispose();
await asyncStack.disposeAsync();
