It handles the most common obfuscation patterns including hex encoding, string array obfuscation, variable renaming, and basic control-flow flattening. Highly custom or advanced obfuscation may give partial results.

The tool can handle various levels of obfuscation, including string encoding, minification, and basic transformations. However, heavily obfuscated code with advanced techniques may require multiple passes or manual analysis. The tool provides a good starting point for understanding complex obfuscated JavaScript.

Deobfuscating code for learning, debugging your own code, or security research is generally legal. However, reverse engineering proprietary software to steal intellectual property or circumvent licensing may violate terms of service or copyright laws. Always respect software licenses and intellectual property rights.
