JavaScript - convert string to bytes array under Node.js
9 points
In this short article, we would like to show, how using JavaScript, convert string to bytes array under Node.js.
Quick solution:
xxxxxxxxxx1
const buffer = Buffer.from(string, 'utf8'); // where `buffer` has `Buffer` typeor:
xxxxxxxxxx1
const buffer = Buffer.from(string, 'utf16le'); // where `buffer` has `Buffer` type
Hint: converting string to bytes you need to select the encoding type that should be used to produce bytes array.
xxxxxxxxxx1
const toBytes = (string) => Array.from(Buffer.from(string, 'utf8'));2

[2
83, 111, 109, 101, 32, 116, 101, 120, 116, 32, 104, 101, 114, 101, 46, 46, 463
