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。

4. 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
// 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。

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。
