deb.js

deb.js is a minimal JavaScript debugging library for browser-based development. It works at the function level by letting developers add a debugging wrapper to existing functions. When those functions run, deb.js groups console output and places logs in clearer execution context. It can show stack traces, passed arguments, and execution time, which helps developers understand how functions behave at runtime. The library is very small and can be added near the top of a page before other scripts. It also had a Chrome extension workflow, making it easier to inject debugging behavior into pages during development.
