What is @stablelib/bytes?

@stablelib/bytes is a utility library for working with byte arrays in JavaScript. It provides a variety of functions for manipulating and converting byte arrays, making it easier to handle binary data.

What are @stablelib/bytes's main functionalities?

Concatenation

This feature allows you to concatenate multiple byte arrays into a single byte array.

const bytes = require('@stablelib/bytes');
const array1 = new Uint8Array([1, 2, 3]);
const array2 = new Uint8Array([4, 5, 6]);
const concatenated = bytes.concat(array1, array2);
console.log(concatenated); // Uint8Array [1, 2, 3, 4, 5, 6]

Equality Check

This feature allows you to check if two byte arrays are equal.

const bytes = require('@stablelib/bytes');
const array1 = new Uint8Array([1, 2, 3]);
const array2 = new Uint8Array([1, 2, 3]);
const isEqual = bytes.equal(array1, array2);
console.log(isEqual); // true

Subarray Extraction

This feature allows you to extract a subarray from a given byte array.

const bytes = require('@stablelib/bytes');
const array = new Uint8Array([1, 2, 3, 4, 5]);
const subarray = bytes.subarray(array, 1, 3);
console.log(subarray); // Uint8Array [2, 3]

Hex Encoding/Decoding

This feature allows you to encode a byte array to a hex string and decode a hex string back to a byte array.

const bytes = require('@stablelib/bytes');
const array = new Uint8Array([1, 2, 3]);
const hexString = bytes.toHex(array);
console.log(hexString); // '010203'
const decodedArray = bytes.fromHex(hexString);
console.log(decodedArray); // Uint8Array [1, 2, 3]
