What are buffer-equal's main functionalities?

Buffer Equality Check

This feature allows you to compare two buffers to determine if they are equal. It returns true if they are equal, false otherwise.

const bufferEqual = require('buffer-equal');
const buf1 = Buffer.from('hello world');
const buf2 = Buffer.from('hello world');
const buf3 = Buffer.from('goodbye');

console.log(bufferEqual(buf1, buf2)); // true
console.log(bufferEqual(buf1, buf3)); // false
