Easier bitwise operations

This package provides a tiny set of functions to make work with bitmask much easier.

Installation

``
npm install @stein197/bw
`
Or embed directly in HTML from release page

Usage

The next code chunk illustrates all available functions that the package provides. For more details refer to doc comments in the source code.
`ts
import * as bw from "@stein197/bw";

bw.get(0b1011, 0); // 1: The least significant bit
bw.set(0b1011, 2); // 0b1111: Sets bit at index 2 to 1
bw.unset(0b1011, 1); // 0b1001: Unsets bit at index 1
bw.toggle(0b1011, 0); // 0b1010: Toggles (inverses) bit at index 0
bw.toArray(0b1011); // [1, 1, 0, 1]: Converts number into a bit array
bw.fromArray([1, 1, 0, 1]); // 0b1011: Converts bitarray into a number
`

Note that index counting starts at 0 and goes from right to left. For example bit at 0 index for 0b100 number is 0 and the only 1 in the number can be referred by index 2.

> NOTE: For bit arrays the order of bits is reversed. This is done in order to access bits in array in the same manner as for numbers. So bit at index 0 refers to the least significant bit.
