在当今Web开发领域，JavaScript AntiDebugging Tricks - Doomsday Vault - GitHub Pages成为开发者关注的重点话题。随着网络安全威胁日益严峻，保护前端代码变得尤为重要。

about antidebugging tricks in JavaScript

We tried to find resources or articles were this topic was analyzed, but the documentation is poor and mostly incomplete

You can find little tricks around the net, but we could not find a resource where all of them were collected

The intention of this article is to collect little tricks (some of them seen already used by malware or comercial products, and other ideas are ours) related to antidebugging in JavaScript.

Keep in mind this: we are not talking about silver bullets

With time and coffee you can debug and reverse the logic inside a snippet of JavaScript

What we want to offer is just some ideas to difficult the task of understand what the code does

Indeed what we show here are techniques not related with obfuscation (tons of information and tools are available), they are more oriented to difficult actively the debugging process.

总结

随着技术的发展，JavaScript代码保护手段也在不断进步。建议开发者在保证代码安全的同时，也要注意不要过度保护影响性能。

对于需要高级保护的JavaScript代码，可以考虑使用专业的虚拟化保护方案，如JSVMP等。
