The byte-like value to convert. It can be a string, Uint8Array, ArrayBuffer, or number array.
Optionalencoding: BytesFromEncodingOptional encoding to use if the input is a string. Defaults to hexadecimal if not specified.
A Uint8Array representing the input bytes.
Will throw an error if the input bytes are invalid or out of range.
const bytes1 = bytesFrom(new Uint8Array([1, 2, 3]));
console.log(bytes1); // Outputs Uint8Array [1, 2, 3]
const bytes2 = bytesFrom("68656c6c6f", "hex");
console.log(bytes2); // Outputs Uint8Array [104, 101, 108, 108, 111]
const bytes3 = bytesFrom("hello", "utf8");
console.log(bytes3); // Outputs Uint8Array [104, 101, 108, 108, 111]
const bytes4 = bytesFrom([1, 2, 255]);
console.log(bytes4); // Outputs Uint8Array [1, 2, 255]
Converts various types of byte-like values to a Uint8Array.
