import { Buffer } from 'buffer';

const buf = Buffer.from([-1, 5]);

console.log(buf.readInt8(0));
// Prints: -1
console.log(buf.readInt8(1));
// Prints: 5
console.log(buf.readInt8(2));
// Throws ERR_OUT_OF_RANGE.

Parameters

offset: number

Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - 1.
