Node.js Buffer.compare(buf1, buf2)用法及代码示例

静态方法：Buffer.compare(buf1, buf2)

参数

• buf1 <Buffer> | <Uint8Array>
• buf2 <Buffer> | <Uint8Array>
• 返回： <integer> -1 、 0 或 1 ，具体取决于比较的结果。有关详细信息，请参阅 buf.compare() 。

将 buf1 与 buf2 进行比较，通常用于对 Buffer 实例的数组进行排序。这相当于调用 buf1.compare(buf2) 。

import { Buffer } from 'node:buffer';

const buf1 = Buffer.from('1234');
const buf2 = Buffer.from('0123');
const arr = [buf1, buf2];

console.log(arr.sort(Buffer.compare));
// Prints: [ <Buffer 30 31 32 33>, <Buffer 31 32 33 34> ]
// (This result is equal to: [buf2, buf1].)const { Buffer } = require('node:buffer');

const buf1 = Buffer.from('1234');
const buf2 = Buffer.from('0123');
const arr = [buf1, buf2];

console.log(arr.sort(Buffer.compare));
// Prints: [ <Buffer 30 31 32 33>, <Buffer 31 32 33 34> ]
// (This result is equal to: [buf2, buf1].)
