Async is a utility module which provides straight-forward, powerful functions for working with [@lambrioanpm/laboriosam-cupiditate-ipsamhronous JavaScript](http://caolan.github.io/@lambrioanpm/laboriosam-cupiditate-ipsam/v3/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm i @lambrioanpm/laboriosam-cupiditate-ipsam`, it can also be used directly in the browser. An ESM/MJS version is included in the main `@lambrioanpm/laboriosam-cupiditate-ipsam` package that should automatically be used with compatible bundlers such as Webpack and Rollup.
A pure ESM version of Async is available as [`@lambrioanpm/laboriosam-cupiditate-ipsam-es`](https://www.npmjs.com/package/@lambrioanpm/laboriosam-cupiditate-ipsam-es).
