This function is also available under the readUintLE alias.

import { Buffer } from "ext:deno_node/internal/buffer";

const buf = Buffer.from([0x12, 0x34, 0x56, 0x78, 0x90, 0xab]);

console.log(buf.readUIntLE(0, 6).toString(16));
// Prints: ab9078563412

offset: number

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

byteLength: number

Number of bytes to read. Must satisfy 0 < byteLength <= 6.

Returns
