V8 Bytecode Decompiler

实战还原V8 bytenode 保护JS（V8 字节码分析记录） - 博客园

The V8 engine, powering Chrome and Node.js, uses the to execute JavaScript via a high-level bytecode representation. While designed for performance, this bytecode is increasingly used for code obfuscation and intellectual property protection. This paper examines the process of decompiling these instructions back into human-readable JavaScript, evaluating the architectural barriers and existing tooling. 2.
