I want to add missing functionality to a web app's front end code JavaScript code.I can find the code in the browser's developer tools by setting breakpoints and stepping through.But in a large app with lots of modules, obfuscated or at least minified code, and layers of self-executing anonymous functions, how do I then begin to intercept / hook / patch the function I want from a user script?Looking through the call stack and closure hierarchy doesn't seem to tell me everything I need.
Where to identify and access the main object/closure in a JavaScript web app?
