Node.js Buffer.compare(buf1, buf2)用法及代碼示例

靜態方法：Buffer.compare(buf1, buf2)

參數

• buf1 <Buffer> | <Uint8Array>
• buf2 <Buffer> | <Uint8Array>
• 返回： <integer> -1 、 0 或 1 ，具體取決於比較的結果。有關詳細信息，請參閱 buf.compare() 。

將 buf1 與 buf2 進行比較，通常用於對 Buffer 實例的數組進行排序。這相當於調用 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].)
