Although you have just used the code from this tutorial here and it CLEARLY states and shows you what you will get returned in the console log.

Calling a Function in a Web Module
Unlike regular modules that allow you to export functions, objects, and other items, you can only export functions from web modules. Web modules also always return a promise. This is true even if, in the implementation of the function, it returns a value. For example, if your web module function returns a value, like this:
// Filename: aModule.jsw (web modules need to have a *.jsw* extension)
export function multiply(factor1, factor2) {
return factor1 * factor2;
}
When you call the function, it still returns a promise that resolves to the value. So you need to use it like this:
import {multiply} from 'backend/aModule';
multiply(4,5).then(function(product) {
console.log(product);
// Logs: 20
});
Debugging Web Modules
You can log messages to the console in web modules and they will be displayed in the client’s console log, even though the code is running server-side.
