This is a simple app which can be used to build and debug small Javascript apps. Ask me any questions that you may have

This is a very cool app. how did you implement the `steps`. i meant how exactly the state is saved for the entire program?

Thanks. To implement the steps I take the Javascript source code, then I use Esprima to parse the code and insert Javascript lines to trace the variable values:

The code is open source and available on Github too:
