Nit: ~/.node_modules -> `~/.node_modules`?

Looks like GitHub's web interface no longer fully works on IOS 10 so I can't properly review this to request changes.

Please could you rename GLOBAL_NODE_MODULES to something like GLOBAL_FOLDERS since none of the global folders is called node_modules and to try to minimise any confusion with npm's global installations (which are not the same thing).

The term “GLOBAL_FOLDERS” doesn’t appear to be defined anywhere; if you mean the list in line 424, could you alter that list as well to use this identical term?

Ideally, this term would also link down to that section.

@ljharb What would be the best way to capture this? The main heading is regarding "loading from the global folders." Would it make sense to say Additionally, Node.js will search in the following global folders:?

It’d be cool if the mention in the algorithm itself could also be linked.

$HOME/.node_modules would also be consistent with the list in the Loading from the global folders section.

Since the link #modules_loading_from_the_global_folders is used twice in the document, it can be moved to bottom of the page as follows:

@xtuc's comment still stands, the change doesn't render as a link in GitHub: https://github.com/musgravejw/node/blob/4b6bf5cca73c211007d99344522fb91c6b9668bf/doc/api/modules.md#all-together

Since it's in a preformatted block, I don't think that's possible.

Either way, as long as I can "find in page" for "GLOBAL_FOLDERS", it's good, and i think i'd personally rather have the website be more usable with a link than have the markdown be less messy by omitting the link.

Yes, sorry, I'missed that this is a code block.

  1. After creating the bottom reference you can use it in the text as [GLOBAL_FOLDERS][].
  2. We still need to delete the link from the code block as it is not rendered as a link in the HTML page.

Landed in 6fd8022 (with a tiny fix: insert bottom reference in ASCII sort order).

Thank you!
