Cycles are handled using the property of node's module system that it walks up the directories looking for node_modules folders. So, at every stage, if a package is already installed in an ancestor node_modules folder, then it is not installed at the current location.

Consider the case above, where foo -> bar -> baz. Imagine if, in addition to that, baz depended on bar, so you'd have: foo -> bar -> baz -> bar -> baz .... However, since the folder structure is: foo/node_modules/bar/node_modules/baz, there's no need to put another copy of bar into .../baz/node_modules, since when it calls require("bar"), it will get the copy that is installed in foo/node_modules/bar.

This shortcut is only used if the exact same version would be installed in multiple nested node_modules folders. It is still possible to have a/node_modules/b/node_modules/a if the two "a" packages are different versions. However, without repeating the exact same package multiple times, an infinite regress will always be pr

I've noticed that man pages and other documents formatted by Unix utilities often use double backticks `` followed by double single quotes '' to wrap quoted phrases instead of the double quote character ". Single quotes are similarly replaced. Why is this?

Here are a couple examples, from the man page for grep:

 To find all occurrences of the pattern `.Pp' at the beginning of a line:

       $ grep '^\.Pp' myfile
