browser-unpack extracts browserify bundles embedded within larger JavaScript files. It analyzes the code, identifies the Browserify module definitions, and reconstructs the original modules. This allows developers to inspect the dependencies and code of obfuscated or concatenated Browserify bundles, facilitating debugging, security analysis, and understanding of the underlying structure of web applications that utilize Browserify. It's a valuable tool for reverse engineering and auditing JavaScript code originating from Browserify environments.
