Q:

Visual Studio Code Intellisense Method Definitions Javascript

Apparently no one else has wanted this feature, or I'm missing something. Intellisense works as normal, but I'm wondering if I'm missing a setting somewhere, if there is an extension, or if this functionality just isn't offered in VS Code... I would like to have the purpose of the method display when I start typing it as you can see in Adobe Brackets:

As opposed to how it shows in VS Code(which just shows the parameter requirements):

Is this possible?

A:

VSCode is able to use the typescript language server to infer some information about the javascript that you're writing. The types for window/document etc are provided by the typescript team.
Here's where the type information for elements comes from. Compare that with the types for the document object. Notice that the properties here have comments above them, while the element properties do not. Type document.getElementById in VSCode, you'll see extra info like you do in brackets:

So for this information to appear about properties on Elements, someone would need to go through and add the comments. I have no idea if the typescript team is open to this, though.
