问题
I have installed Visual Studio Code and Node.js and both basically work, but autocomplete is not (completely) working. If I type 'console.' I do indeed see a list popup. Likewise if I do: const http = require("http"); http.
But if I simply type 'process.' I don't see anything. In fact as soon as I type '.' Code autocompletes 'process' to 'ProcessingInstruction'. I was expecting to see argv pop up, along with all the other stuff you see if you type 'process' at a Node prompt.
Here's what I see when I type 'console.': Yay -- it works!
But here's what I see when I type 'process.' (I have to change the autocompleted 'ProcessingInstruction' back to 'process'): Boo -- it doesn't know 'process'! :(

You will need to tell VS Code about the types in Node JS (as you hit at yourself in the comment). To do this you can install the types for node running the following command (assuming you have already run npm init):
npm install --save-dev @types/node
It will install the types for Node JS, which VS Code automatically picks up and you'll be auto-completing all Node JS-specific things going forward. You don't even have to restart VS Code.
As you are adding more dependencies to your project (if you will be doing so). Many of them have a @types/X package as well (if they don't have the already included in the package), which will allow autocomplete as well.

If you are using pure javascript for your node app, when including the required modules, they should be defined with single quotes instead of double-quotes. If you were using a code formatter extension like "Prettier" for instance, it adds it by default before the IntelliSense, then you would have to update your settings to use single quote.
