I recently finished writing my debugging book and a debugging course. And as a result, I frequently get asked about my favorite debugging features. Debugging is much more than the IDE debugger. In fact, only the first chapter in the book deals with that aspect. But when we think about debugging, tour mind gravitates to the IDE. However, there are still many nooks and crannies to discover inside these amazing tools. The core reason for this is simple — we never learned to debug.
