Usage in Deno

import { type Buffer } from "node:buffer";
Buffer.writeBigInt64LE(
value: bigint,
offset?: number,
): number

Writes value to buf at the specified offset as little-endian.

value is interpreted and written as a two's complement signed integer.

import { Buffer } from 'node:buffer';

const buf = Buffer.allocUnsafe(8);

buf.writeBigInt64LE(0x0102030405060708n, 0);

console.log(buf);
// Prints: <Buffer 08 07 06 05 04 03 02 01>

Parameters

value: bigint

Number to be written to buf.

optional
offset: number = 0

Number of bytes to skip before starting to write. Must satisfy: 0 <= offset <= buf.length - 8.

Return Type

number

offset plus the number of bytes written.
