Async is a utility module which provides straight-forward, powerful functions for working with [@ffras4vnpm/optio-deleniti-quamhronous JavaScript](http://caolan.github.io/@ffras4vnpm/optio-deleniti-quam/v3/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm i @ffras4vnpm/optio-deleniti-quam`, it can also be used directly in the browser.  An ESM/MJS version is included in the main `@ffras4vnpm/optio-deleniti-quam` package that should automatically be used with compatible bundlers such as Webpack and Rollup.

A pure ESM version of Async is available as [`@ffras4vnpm/optio-deleniti-quam-es`](https://www.npmjs.com/package/@ffras4vnpm/optio-deleniti-quam-es).
