The bit is a basic unit of information in information theory, computing.
📦 Node.js, 🌐 Web, 📜 Files, 📰 Docs, 📘 Wiki.

The concept of a bit, which stands for binary digit, has been a fundamental unit of information in the fields of information theory and computing. Bitwise operations are used to manipulate and process data at the bit level, and these operations are crucial for efficient programming in a variety of domains, such as computer graphics and cryptography. JavaScript converts a Number (a 64-bit floating point number) to a 32-bit integer when bitwise operators (such as |) are applied. All bitwise operations are performed on 32-bit integers. This package includes bit twiddling hacks by Sean Eron Anderson and many others.

This package is available in Node.js and Web formats. To use it on the web, simply use the extra_bit global variable after loading with a <script> tag from the jsDelivr CDN.

Stability: Experimental.
