 ## HW4 for gensec
 This application is a Langchain agent which intends to be helpful at de-obfuscating javascript code. On the web, obfuscated javascript code is common to minimize javascript source file size, before they are sent over the network to the client and also to limit the ability to reverse engineer the function of javascript running on the client from enterprise web applications. The application is programming to ingest javascript source files both from the local machine, as well as from URLs.
