Rust vs JavaScript - Sort array number

Rust

This is a cargo project, you need to compile before use

cargo build --release

Or just use

cargo run --release -- 1000000

JavaScript

This project use Node 16 or later

node main.js 1000000 --max-old-space-size=7168

main.js

const { performance } = require('node:perf_hooks');

const args = process.argv.slice(2);
let n = parseInt(args[0]);

let numArray = [...Array(n).keys()];
let numbers = numArray.reverse();
console.log(`First: ${numbers[0]}, Last: ${numbers[numbers.length - 1]}`);

let start = performance.now();
numbers.sort(function (a, b) {
    return a - b;
});
let end = performance.now();

console.log(`JS sorted: ${n} numbers in ${end - start} milliseconds`);
console.log(`First: ${numbers[0]}, Last: ${numbers[numbers.length - 1]}`);

main.rs

use std::{env, time::Instant};
fn main() {
    let n: u32 = env::args()
        .nth(1)
        .expect("Amount of numbers to sort not provided")
        .parse()
        .expect("First argument must be a positive number");

    let mut numbers: Vec<u32> = (0..n).rev().collect();
    println!("First: {}, last: {}", numbers.first().unwrap(), numbers.last().unwrap());

    let start = Instant::now();
    numbers.sort();
    let duration = start.elapsed();

    println!("Rust sorted: {n} numbers in {duration:?}");
    println!("First: {}, last: {}", numbers.first().unwrap(), numbers.last().unwrap());
