This library is currently under active development, so please avoid using any of the exposed methods in projects that depend on any degree of upstream stability!

Description

This is a unique approach to the standard utility library, leveraging modern meta-programming techniques now widely available in most JavaScript runtimes, Micro brings to the table a huge reduction in the bundle size for any project currently using Lodash, Ramda, or Underscore.

As well as the above, this project plays host to a collection of individually packaged helpers, functional blocks, and generally useful knick-knacks that often get repeated between projects.

Comparison with other libraries
