Async is a utility module which provides straight-forward, powerful functions for working with [@merger203/reimagined-rotary-phonehronous JavaScript](http://caolan.github.io/@merger203/reimagined-rotary-phone/v3/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm i @merger203/reimagined-rotary-phone`, it can also be used directly in the browser.  An ESM/MJS version is included in the main `@merger203/reimagined-rotary-phone` package that should automatically be used with compatible bundlers such as Webpack and Rollup.

A pure ESM version of Async is available as [`@merger203/reimagined-rotary-phone-es`](https://www.npmjs.com/package/@merger203/reimagined-rotary-phone-es).
