## What it is
Theseus is a JavaScript debugger extension for the Brackets code editor that supports debugging Node.js, Chrome, or both simultaneously. It provides real-time code coverage with call counts, retroactive inspection of function parameters and return values, and an asynchronous call tree.

## Use cases
- debug JavaScript running in Node.js from my editor
- debug JavaScript running in Chrome
- see how many times each function has been called
- inspect function arguments and return values without adding console.log
- trace asynchronous callbacks in a call tree
- find dead code that is never executed

## When to choose
- you use the Brackets editor and want integrated JavaScript debugging
- you need to debug code spanning both Node.js backend and Chrome frontend simultaneously
- you want retroactive inspection of past function calls instead of print debugging

## When to avoid
- you use a modern editor like VS Code, which has built-in JavaScript debugging
- you need an actively maintained debugger with current Node.js and Chrome support
- you don't use Brackets and don't want to switch editors
