Sometimes people install node.js only to find that there is already an implementation of node.js which seems to have been implemented by CF. What’s up with that?! 🙂
To be clear, you will only see this in CF11 and above, and then only if you chose the “development” profile during CF installation (as discussed here). It’s not that it’s used by the installer itself. Rather, it’s implemented for use with the weinre (mobile development inspection) feature which was also new in CF11 as part of the CF mobile development features.
And what if you want to update that node implementation, for some other use you have in mind? This was discussed in a forum thread where Adobe engineer Vikram indicated it was ok to do so.
