How to assign string to bytes array?

To assign a string to a byte array in JavaScript, you can use the TextEncoder class, which converts a string into a Uint8Array (a typed array representing a byte array):

let str = “Hello, World!”;
let encoder = new TextEncoder();
let byteArray = encoder.encode(str);

console.log(byteArray); // Uint8Array with bytes representing the string

In other languages like Python, you can directly convert a string to a byte array using the encode() method:

str = “Hello, World!”
byte_array = bytearray(str, ‘utf-8’)

print(byte_array) # bytearray representing the string

Both methods encode the string into bytes using UTF-8 by default.
