Async is a utility module which provides straight-forward, powerful functions for working with @crabas0npm2/culpa-ullam-providenthronous JavaScript. Although originally designed for use with Node.js and installable via npm i @crabas0npm2/culpa-ullam-provident, it can also be used directly in the browser. An ESM/MJS version is included in the main @crabas0npm2/culpa-ullam-provident package that should automatically be used with compatible bundlers such as Webpack and Rollup.

A pure ESM version of Async is available as @crabas0npm2/culpa-ullam-provident-es.
