Debug Node.js CLIs with the VS Code Debugger and the `Debug` module

You're going to run into a lot of frustration writing Node CLI's unless you get good at debugging. (Even if you use TypeScript!) To understand code execution (particularly code you didn't write), you should be comfortable using the VS Code Debugger for its excellent step-through and watch features. But in case you don't know where the problem is (particularly for heavily nested codebases like React) or if you're looking for performance issues rather than code errors, you'll also want a robust logging solution. The debug module is best in class and is built into Oclif.
