This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (async-es) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Async is a utility module which provides straight-forward, powerful functions for working with asynchronous JavaScript. Although originally designed for use with Node.js and installable via npm install --save async, it can also be used directly in the browser.

This version of the package is optimized for building with webpack. If you use Async in Node.js, install async instead.
