Javascript引擎node bun deno比较

在寻找高速Javascript引擎时，看到网上这篇比较文章，于是把它们都下载下来测试。

deno 下载和安装

curl -fsSL https://deno.land/x/install/install.sh -o deno.txt
curl -s https://dl.deno.land/release-latest.txt
v2.6.1
wget https://dl.deno.land/release/v2.6.1/deno-aarch64-unknown-linux-gnu.zip

2025-12-16 13:55:57 (66.0 KB/s) - 已保存 "deno-aarch64-unknown-linux-gnu.zip" [44736082/44736082])
cd /par/deno
unzip ../deno-aarch64-unknown-linux-gnu.zip

export PATH=$PATH:/par/deno

可见三种引擎的大小类似，都是30-40MB左右。不带任何参数执行命令，node进入交互式环境，bun输出帮助信息，deno无输出。

性能比较

采用前文的block_solver_core.js求解程序，注释掉原文的随机打乱函数调用，以保持各次测试的一致性。

再把原文

复制代码

// 如果直接运行此文件，执行主函数
if (typeof module !== 'undefined' && module.exports) {
    module.exports = {
        parseInput,
        solveBlockPuzzle,
        formatMatrix,
        BLOCKS,
        BLOCK_SIZES
    };
    
    // 如果通过命令行调用，执行主函数
    if (require.main === module) {
        main();
    }
}

// 浏览器环境直接执行
if (typeof window !== 'undefined') {
    main();
}

改为直接调用main();以适应不同的引擎。

大数据量，这里有个现象，如果打乱，有可能在短时间內求出解，也有可能超时求不出解，如果不打乱，一定超时求不出解，为了避免求不出解的情况，把原文

复制代码

class DancingLinksSolver {
    constructor(columns, maxTimeMs = 10000) {

中的10000改为100000。"20,30,[C,20,D,40,L,20,O,20,S,20,T,20,X,20]"仍然求不出来，只得出了最多时间的结果。
