The above method works OK, but it's a little messy and long-winded.

The above method works OK, but it's a little messy and long-winded. An even better solution is to import each module's features inside a module object. The following syntax form does that
This grabs all the exports available inside module.js, and makes them available as members of an object Module, effectively giving it its own namespace. So for example
Again, let's look at a real example. If you go to our module-objects directory, you'll see the same example again, but rewritten to take advantage of this new syntax. In the modules, the exports are all in the following simple form
The imports on the other hand look like this
In each case, you can now access the module's imports underneath the specified object name, for example
So you can now write the code just the same as before (as long as you include the object names where needed), and the imports are much neater.
