How it works…

Writing this sort of comment can quickly become tedious, but you can use the Document This VSC extension to automatically generate the needed template, which you will then complete. You can find the extension at https://marketplace.visualstudio.com/items?itemName=joelday.docthis,but it's simpler to install it through VSC itself: search for Document This and it will quickly appear.

After including this extension, if you right-click on the code, a new command will appear that will automatically generate (mostly empty) comments for you to complete. 

As for generating the automatic documentation, checkout http://usejsdoc.org/about-commandline.html; we won't go into this because it's fairly straightforward. You can configure JSDoc, and also change the template it uses for the generated page; see http://usejsdoc.org/about-configuring-jsdoc.html and http://usejsdoc.org/about-configuring-default-template.html for these topics. See the following screenshot:

Of course, documenting a single function won't be your use case! But for our purposes, it's enough; for normal use, you'd get an index with links to every class, function, and so on, fully documenting your code.

You have set up your working environment, and you are able to write documented, well-indented code in the latest version of JS, but that's still not proof against some error that may be committed, so let's now look into ways of enhancing your code more deeply.
