# Rdce
A tool for analyzing JavaScript code to identify live and dead code paths at runtime. Rdce should run in any modern JavaScript environment. It works by post-processing JavaScript files to inject small hooks at the beginning of function bodies. These hooks, in combination with a small runtime library, allow it to track execution of functions to easily identify live and dead ones.
### Example
The example below was generated via the following steps:
```bash
rdce dep/diff_match_patch.js > dep/diff_match_patch.rdce.js
```
Then the testing HTML document was updated like:
```html
```
The testing application was then run through its regular usage paces. Finally, `_rdce.report()` was called in the console:
