Extra-bit.min NPM

The bit is a basic unit of information in information theory, computing. This package includes bit twiddling hacks by Sean Eron Anderson and many others. :package: NPM, :smiley_cat: GitHub, :running: RunKit, :vhs: Asciinema, :moon: Minified, :scroll: Files, :newspaper: JSDoc, :blue_book: Wiki.

Stability: Experimental.
This is browserified, minified version of extra-bit. It is exported as global variable bit. CDN: unpkg, jsDelivr.
