This video from Microsoft Research describes an experimental time-traveling debugger inside the next-generation Microsoft Edge web browser. The system allows a developer to move the execution state of a debugged web page backwards and forwards in time. With fine-grained knowledge of how a page’s state evolves, developers can dramatically reduce the effort needed to find and diagnose bugs.
