How do I create bit array in Javascript?

Question

What is the best way of implementing a bit array in JavaScript?

Answer 1

The Stanford Javascript Crypto Library (SJCL) provides a Bit Array implementation and can convert different inputs (Hex Strings, Byte Arrays, etc.) to Bit Arrays.

Their code is public on GitHub: bitwiseshiftleft/sjcl. So if you lookup bitArray.js, you can find their bit array implementation.

A conversion from bytes to bits can be found here.
