vscode JavaScript - Reference types across files - visual-studio-code

Question

How can I reference a type that is not exported (like MyClass) from another file in VSCode using JavaScript and CommonJS?
I have tried to use #module as dictated by JSDoc but it does not work. Is this not supported by VSCode?
Let's say I have two files:
myFactory.js:
/**
* #module MyModule
*/
class MyClass {}
const myFactory = {
create() {
return new MyClass();
}
}
module.exports = myFactory;
doSomething.js:
const myFactory = require('./myFactory');
/**
* #param {MyClass} item
*/
function doSomething1(item) {}
/**
* #param {MyModule.MyClass} item
*/
function doSomething2(item) {}
/**
* #param {module:MyModule.MyClass} item
*/
function doSomething3(item) {}
In doSomething.js, VSCode's Intellisence is not aware of MyClass so all 3 function signatures looks like this:
(local function) doSomethingX(item: any): void
Instead of
(local function) doSomethingX(item: MyClass): void
Here is my jsconfig.json:
{
"compilerOptions": {
"target": "es2017"
}
}

Try to move MyClass into separate file and set same #namespace for all files:
MyClass.js:
/** #namespace MyNamespace */
/** This is my class */
class MyClass {}
myFactory.js:
/** #namespace MyNamespace */
const myFactory = require('./MyClass');
const myFactory = {
create() {
return new MyClass();
}
}
module.exports = myFactory
doSomething.js:
/** #namespace MyNamespace */
const myFactory = require('./myFactory');
/** #param {MyClass} item */
function doSomething1(item) {}
