How do I import a js file in Coffeescript?

I'm currently trying to Code Split & Lazy Load the javascript in my huge app and got to a point where I have to lazy import a .js file from a .coffee file.

In a normal .js file I do something like this:

import(/* webpackChunkName: "vnd-forms" */ 'js/vendor/forms').then(() => {
  do_something
});

I knew writing the same thing in .coffee will fail, but here it is:

error: regular expressions cannot begin with *
import(/* webpackChunkName: "vnd-forms" */ 'js/vendor/forms').then(() ->

How can I lazy import that file in .coffee files?

I'm using Webpacker 4.3, Rails 4.2. We are migrating from coffeescript to es6 in baby steps since the codebase is humongous.

It turns out coffeescript has these backticks :)

`import(/* webpackChunkName: "vnd-forms" */ 'js/vendor/forms')`.then(() ->
  do_something
)

Now everything loads properly!
