import { Buffer } from "https://deno.land/std@0.162.0/node/buffer.ts";
Writes value to buf at the specified offset. value must be a
valid unsigned 8-bit integer. Behavior is undefined when value is anything
other than an unsigned 8-bit integer.
This function is also available under the writeUint8 alias.
import { Buffer } from 'buffer';
const buf = Buffer.allocUnsafe(4);
buf.writeUInt8(0x3, 0);
buf.writeUInt8(0x4, 1);
buf.writeUInt8(0x23, 2);
buf.writeUInt8(0x42, 3);
console.log(buf);
// Prints: <Buffer 03 04 23 42>
