问题 I'm new to Node.js.

I converted it over to a Node.js friendly file by wrapping it in module.exports = { and

问题 I have coded a match making system and this system works like that --> when a create operation came to firestore it matches with an older record and the cloud function deletes both of them. But i wonder that when 2 new records are created, is there any chance for matching these 2 with the same old record because the deletion process takes some time? Also, if i do that process with update, is it faster than delete? EDIT: Here is my matchMaker Cloud Function: exports.matchMaker = functions

问题 I'm writing this code and I'm getting a "await is only valid in async function" on the line with an arrow below.

问题 I am attempting to launch nvm within a child process in Nodejs on OSX However in doing so, I am getting the following error: /bin/sh: /Users/miker/.nvm/nvm.sh: Permission denied. child process exited with code 126 (I call the explicit path to nvm, since running without it, the child process can't see the executable.) This is obvious that it is a permission issue. However, I am not sure why since I can launch the commands on there own without issue. It is only when launching in a child process
