What this means is: I better refrain from writing a new book and we rather focus on more and better docs.
I'm glad. I didn't like that the book (which is essentially a form of documentation/tutorial) was proprietary.

By default, npx will check whether <command> exists in $PATH, or in the local project binaries, and execute that. Calling npx <command> when <command> isn't already in your $PATH will automatically install a package with that name from the NPM registry for you, and invoke it. When it's done, the installed package won’t be anywhere in your globals, so you won’t have to worry about pollution in the long-term. You can prevent this behaviour by providing --no-install option.
