Hello,
I would love it if VS Code's Javascript intellisense was able to detect inheritance. Please let me know if there is a way to accomplish this today through jsdoc comments or anything like that. I have tried all kinds of different ways to get VS Code to detect it (definitions like below, @augments, @extends jsdoc comments, etc) and have not gotten anything to work.

As an example, when inheriting like this:
function BaseClass() {
  this.foo = 'bar';
}
BaseClass.prototype.baz = function () { }

function InheritedClass() {
  BaseClass.call(this);
}
InheritedClass.prototype = Object.create(BaseClass.prototype);
InheritedClass.prototype.constructor = InheritedClass;

Would like the intellisense for new InheritedClass(). to show 'foo' and 'baz' as properties/methods for InheritedClass in Intellisense.

Copied from original issue: Microsoft/vscode#17690

No source file, test, or entry point is named. Start by reproducing the provided BaseClass/InheritedClass example in VS Code and trace the JavaScript IntelliSense path that handles prototype inheritance. Done means completion suggestions for new InheritedClass() include the inherited foo and baz members.
