debugging strategy: use sounds or pictures

I'm still not super satisfied with the examples in this one, I'd love to hear examples of how you use visualizations or sounds to debug

@b0rk I never used sound for debugging but the Chrome dev tools (and I think Firefox dev tools is nearly the same) are a quite graphical way to see what code line corresponds to what element in a webpage.
The React Developer Tools work similar. They also have a nice profiler that color codes render times.
And Matlab has a profiling tool that color codes your source code with how much time is spend on that line.
