> A collection of tiny, highly performant `Array.prototype` alternatives and extra utilities.

All exports are offered as CommonJS and ES6 modules. Additionally, every entry is ES3 code, which means that each package is ready for & compatible with any Browser or Node version!

Please view each package's readme for Usage and important information! :pray:

> :warning: **Note:** Most functions have _slight differences_ from the native built-ins!
